abstract = {The $\alpha$ resonant scattering on $^{18}$Ne was measured in inverse kinematics to understand the $\alpha$-clustering of proton-rich $^{22}$Mg nucleus, performed at the CNS Radio-Isotope Beam Separator (CRIB) of Center for Nuclear Study, University of Tokyo, located at the RIBF of RIKEN Nishina Center. The excitation function of $^{22}$Mg was obtained for the excitation energies of 10--16 MeV by adopting the thick-target method. Several resonances were evident in the present work, which implies the existence of energy levels with large $\alpha$ widths. Since energy levels were not clearly observed at the astrophysically important energy range, upper limits on the $^{18}$Ne ($\alpha$, $\alpha$)$^{18}$Ne cross section were set. The astrophysical impact was also investigated by estimating the $^{18}$Ne ($\alpha$, p)$^{21}$Na cross section.}

doi = {10.1038/s41467-022-34767-8},
abstract = {The dynamics of a nuclear open quantum system could be revealed in the correlations between the breakup fragments of halo nuclei. The breakup mechanism of a proton halo nuclear system is of particular interest as the Coulomb polarization may play an important role, which, however, remains an open question. Here we use a highly efficient silicon detector array and measure the correlations between the breakup fragments of 8B incident on 120Sn at near-barrier energies. The energy and angular correlations can be explained by a fully quantum mechanical method based on the state-of-the-art continuum discretized coupled channel calculations. The results indicate that, compared to the neutron halo nucleus 6He, 8B presents distinctive reaction dynamics: the dominance of the elastic breakup. This breakup occurs mainly via the short-lived continuum states, almost exhausts the 7Be yield, indicating the effect of Coulomb polarization on the proton halo state. The correlation information reveals that the prompt breakup mechanism dominates, occurring predominantly on the outgoing trajectory. We also show that, as a large environment, the continuum of 8B breakup may not significantly influence elastic scattering and complete fusion.}

title = {Constraining the Primordial Lithium Abundance: New Cross Section Measurement of the 7Be$\mathplus$n Reactions Updates the Total $^7$Be Destruction Rate},
journal = {The Astrophysical Journal Letters},
abstract = {The cosmological lithium problem (CLP) stems from the outstanding discrepancy between theoretical predictions and astronomical observations of primordial lithium abundances. For the radiogenic production of 7Li, 7Be plays a pivotal role in the Big Bang nucleosynthesis (BBN). Nevertheless, the data for neutron-induced 7Be destruction processes were still sparse, and especially lacked information on the contributions of transitions to the 7Li excited states. In this work, we have determined the 7BeLi, 7BeLi*, and 7BeHe reaction cross sections by means of the Trojan Horse method. The present and the previous data were analyzed together by a multichannel R-matrix fit, providing an improved uncertainty evaluation of the channel and the first-ever quantification of the contribution in the BBN-relevant energy range. We implemented the revised total reaction rate summing both the and contributions in a state-of-the-art BBN code PRIMAT. As a consequence, the present nuclear-physics data offers a reduction of the predicted 7Li abundance by about one-tenth, which would impose a stricter constraint on BBN and head us in the correct direction to the CLP solution.}

abstract = {The mechanism of reactions with weakly-bound proton-rich nuclei at energies near the Coulomb barrier is a long-standing open question owing to the paucity of experimental data. In this study, a complete kinematics measurement was performed for the proton drip-line nucleus 17F interacting with 58Ni at four energies near the Coulomb barrier. Thanks to the powerful performance of the detector array, exhaustive information on the reaction channels, such as the differential cross sections for quasielastic scattering, exclusive and inclusive breakup, as well as for fusion-evaporation protons and alphas, was derived for the first time. The angular distributions of quasielastic scattering and exclusive breakup can be described reasonably well by the continuum-discretized coupled-channels calculations. The inclusive breakup was investigated using the three-body model proposed by Ichimura, Austern, and Vincent, and results indicate the non-elastic breakup is the dominant component. The total fusion cross sections were determined by the fusion-evaporation protons and alphas. Based on the measured exclusive breakup data, the analysis of the classical dynamical simulation code PLATYPUS demonstrates that the incomplete fusion plays a minor role. Moreover, compared with 16O+58Ni, both the reaction and total fusion cross sections of 17F+58Ni exhibit an enhancement in the sub-barrier energy region, which mainly arises from couplings to the continuum states. This work indicates that the information of full reaction channels is crucially important to comprehensively understand the reaction mechanisms of weakly bound nuclear systems.}

abstract = {We report on the development of a new, portable detector array for charged particles with a low detection threshold to study the reaction mechanisms of exotic nuclear systems at energies around the Coulomb barrier. In order to identify both light and heavy particles simultaneously, the array consists of ten units of $\Delta$E-E telescopes, where each one is made up of four detection layers: one ionization chamber, one 40 (or 60)$\mu$m double-sided silicon strip detector and two quadrant silicon detectors with thicknesses of 300$\mu$m and 1000 (or 1500)$\mu$m, respectively. The frame of the ionization chamber is innovatively designed with printed circuit boards, thus the mass of each telescopic unit was reduced significantly which eases transport and installation requirements to different radioactive ion beam lines around the globe. The commissioning experiments focused on elucidating several reaction mechanisms encountered in the 17F + 58Ni and 17F + 208Pb systems, and we demonstrated that the array has a sufficient capability to enable charged particle identification over a large range of Z. Light particles like p, d, $\alpha$ as well as heavy ions like 16O and 17F can be clearly distinguished. Considering these properties, this newly developed array enables in-depth investigation of the novel reaction mechanisms which are manifested in the collisions of exotic nuclei with differing isotopes.},

One of the methods for investigating 19Ne parameters is studying the mirror nucleus 19F. $\alpha$ elastic scattering experiment was performed with a 7 MeV/u 15N beam for investigating the resonance parameters in 19F using the thick target method in inverse kinematics at the radioactive beam facility CRIB of the Center for Nuclear Study, the University of Tokyo.

abstract = {Abstract It is a well-known fact that a cluster of nucleons can be formed in the interior of an atomic nucleus, and such clusters may occupy molecular-like orbitals, showing characteristics similar to normal molecules consisting of atoms. Chemical molecules having a linear alignment are commonly seen in nature, such as carbon dioxide. A similar linear alignment of the nuclear clusters, referred to as linear-chain cluster state (LCCS), has been studied since the 1950s, however, up to now there is no clear experimental evidence demonstrating the existence of such a state. Recently, it was proposed that an excess of neutrons may offer just such a stabilizing mechanism, revitalizing interest in the nuclear LCCS, specifically with predictions for their emergence in neutron-rich carbon isotopes.
Here we present the experimental observation of $\alpha$-cluster states in the radioactive $^14$C nucleus.
Using the $^{10}$Be + $\alpha$ resonant scattering method with a radioactive beam, we observed a series of levels
which completely agree with theoretically predicted level having an explicit linear-chain cluster configuration.
We regard this as the first strong indication of the linear-chain clustered nucleus. }

abstract = {Software for genuinely event-by-event analysis and event reconstruction of data obtained by using an active target
has been developed in the graphical user interface under the CERN ROOT framework.
The primary motivation for developing the software was to provide physicists
who perform experiments using an active target a more user-friendly environment for
the purpose of investigating the performance of detection systems and obtaining
ideas about physics from a large amount of experimental data. To test the performance of
the software, we analyzed experimental data from a 16N radioactive ion beam experiment for
$\alpha$-decay measurements. As a result of the analysis, we observed the Bragg curve and
measured the range of the 16N RI beam in the detector. Data were calibrated against the
calculation after comparing the Bragg curve to the one obtained from an energy loss calculation
in P-10 gas. We present a detailed description of the analysis software and its test results.},

the compound nucleus $^{22}$Mg have been investigated by measuring the resonant elastic scattering of $^{21}$Na + p. An 89-MeV $^{21}$Na radioactive beam delivered from the CNS Radioactive Ion Beam Separator bombarded an 8.8 mg/cm$^{2}$ thick polyethylene (CH$_{2}$)n target. The $^{21}$Na beam intensity was about 2{\times}10$^{5}$ pps, with a purity of about 70\% on target. The recoiled protons were measured at the center-of-mass scattering angles of {\theta}$_{c.m.}${\approx}175.2$^{\circ}$, 152.2$^{\circ}$, and 150.5$^{\circ}$ by three sets of {$\Delta$}E-E telescopes, respectively. The excitation function was obtained with the thick-target method over energies E$_{x}$($^{22}$Mg)=5.5-9.2 MeV. In total, 23 states above the proton-threshold in $^{22}$Mg were observed, and their resonant parameters were determined via an R-matrix analysis of the excitation functions. We have made several new J$^{\pi}$ assignments and confirmed some tentative assignments made in previous work. The thermonuclear $^{18}$Ne({$\alpha$},p)$^{21}$Na rate has been recalculated based on our recommended spin-parity assignments. The astrophysical impact of our new rate has been investigated through one-zone postprocessing x-ray burst calculations.

abstract = {The evolution of massive stars with very low-metallicities depends critically on the amount of CNO nuclides which they produce. The $^{12}$N(p,$\gamma$)$^{13}$O reaction is an important branching point in the rap processes, which are believed to be alternative paths to the slow 3α process for producing CNO seed nuclei and thus could change the fate of massive stars. In the present work, the angular distribution of the $^{2}$H($^{12}$N, $^{13}$O)n proton transfer reaction at E$_{c.m.}$=8.4 MeV has been measured for the first time. Based on the Johnson-Soper approach, the square of the asymptotic normalization coefficient (ANC) for the virtual decay of $^{13}$O$_{g.s.}$ → $^{12}$N+p was extracted to be 3.92 ± 1.47 fm$^{-1}$ from the measured angular distribution and utilized to compute the direct component in the $^{12}$N(p,$\gamma$)$^{13}$O reaction. The direct astrophysical S factor at zero energy was then found to be 0.39 ± 0.15 keV b. By considering the direct capture into the ground state of $^{13}$O, the resonant capture via the first excited state of $^{13}$O and their interference, we determined the total astrophysical S factors and rates of the $^{12}$N(p,$\gamma$)$^{13}$O reaction. The new rate is two orders of magnitude slower than that from the REACLIB compilation. Our reaction network calculations with the present rate imply that $^{12}$N(p,$\gamma$)$^{13}$O will only compete successfully with the $\beta^{+}$ decay of $^{12}$N at higher (∼2 orders of magnitude) densities than initially predicted.},

abstract = {{Background: In presolar low-density graphite grains, an extraordinarily large $^{22}$Ne/$^{20}$Ne ratio or even nearly pure $^{22}$Ne is found, pointing to the condensation of radioactive $^{22}$Na in grains. Supernovae and neon-rich novae are the main events that produce $^{22}$Na via the explosive hydrogen burning process. The $^{22}$Na(p, {$\gamma$})$^{23}$Mg reaction is one of the key reactions that influences the $^{22}$Na abundance in ejecta.Purpose:The present work aims to explore the proton resonant states in $^{23}$Mg relevant to the astrophysical $^{22}$Na(p, {$\gamma$})$^{23}$Mg reaction. The determined $^{23}$Mg resonant parameters can be used to evaluate the $^{22}$Na(p, {$\gamma$})$^{23}$Mg reaction rate.Method:A low-energy $^{22}$Na radioactive ion beam is produced via the $^{1}$H($^{22}$Ne, $^{22}$Na)n reaction, and used to measure the experimental excitation function of the $^{22}$Na + p resonant scattering with a conventional thick-target inverse kinematic method. R-matrix analysis is applied to deduce the $^{23}$Mg resonance parameters from the experimental excitation function.Results: Three proton resonance states in $^{23}$Mg are observed. Spins/parities and the proton partial widths are determined. The deduced excitation energies agree with the compiled values.Conclusions: The new spin and parity assignments allow us to perform a shell-model calculation of the {$\gamma$} widths of the $^{23}$Mg resonant states for the evaluation of the $^{22}$Na(p, {$\gamma$})$^{23}$Mg astrophysical reaction rate. The two s-wave resonant states established in this work at 8.793 and 8.916 MeV in $^{23}$Mg, respectively, increase the total reaction rate by about 5\% at a temperature greater than 2 GK. }},

In particular, the {$\alpha$}-decay width can be useful information to discuss the {$\alpha$}-cluster structure in $^{11}$C. \\{\bf Methods:} New measurements of $^{7}$Be+{$\alpha$} resonant scattering and the $^{7}$Be({$\alpha$},p)$^{10}$B reaction in inverse kinematics were performed for center-of-mass energy up to 5.5 MeV, and the resonances at excitation energies of 8.9--12.7 MeV in the compound $^{11}$C nucleus were studied.

An intense $^{7}$Be beam (2{\times}10$^{8}$ particles per second) was successfully produced using this target. We observed a density-reduction effect at the gas target for high-current primary beams with about 7.5 W heat deposition. One main feature of the target system is forced circulation of the target gas. We have found that the circulation of the target gas at a rate of 55 standard liters per minute (slm) was effective in eliminating the density reduction. The extent to which the forced flow can prevent the density reduction had not been known well. In this work, the relation between the density reduction and the forced circulation rate was quantitatively studied. }},

We developed a method to produce an unstable 7Be target to measure the reaction in normal kinematics in a high-resolution measurement. We performed an experiment to produce the 7Be target and also to measure the cross section of the 7Be(d, p)8Be reaction with the produced 7Be target at the tandem facility, Kobe University. A 2.36 MeV proton beam irradiated a Li target to transmute 7Li particles to 7Be particles via the 7Li(p, n)7Be reaction. We produced 2.6×10$^{13}$ 7Be particles in the target after two days’ proton irradiation. After the target production, the beam ion was changed to deuterons with energies of 0.6, 1.0, and 1.6 MeV to measure the 7Be(d, p) reaction. The outgoing protons were measured by two $\Delta E-E$ silicon telescopes placed at 30$^{o}$ and 45$^{o}$. We report the preliminary results of this experiment, including the 7Be(d, p) cross section.}

The elastic resonant scattering is a striking tool to study astrophysical reactions and nuclear clusters. In particular, when it is coupled with a thick target and inverse kinematics, the measurement can be very efficient and even feasible with RI beams. By measuring resonant scattering, we can study the properties of resonant states which could play an important role in the astrophysical reaction, or have an exotic nuclear structure. The 10Be+α elastic scattering has been measured at CRIB, and three resonances which are in agreement with the prediction of a linear-chain structure by Suhara-En’yo were observed, giving a strong indication of the existence of such an exotic structure. Measurements based on the indirect technique of the reaction measurement, such as the Trojan horse method, have also been performed at CRIB.}

As 26Al was the first specific radioactivity observed in the Galaxy, its origin has fascinated the nuclear astrophysics community for nearly forty years.
Despite extensive research, the precise origins of 26Al remain elusive.
At present, the sum of all putative stellar contributions generally overestimates the 26Al mass in the
interstellar medium. Among the many reactions that influence the yield of 26Al, radiative proton capture on its isomer
26mAl is one of the least constrained reactions by experimental data. To this end, we developed a 26Al isomeric beam and performed proton elastic scattering to search for low-spin states in 27Si. The experimental method and the preliminary results of this on-going study will be presented.

abstract = { The cosmological 7Li problem has been one of the big issues left in the standard Big-Bang nucleosynthesis (BBN) model. In order to determine the radiogenic 7Li abundance by the BBN, it is important to know the production and the destruction rate of 7Be rather than 7Li itself. We performed indirect measurements
of the relevant neutron-induced reactions 7Be(n, p)7Li and 7Be(n, $\alpha$)4He simultaneously by the Trojan Horse Method (THM) via the three-body reactions 7Be(d,7Lip)1H and
7Be(d, $\alpha \alpha$)1H. A 7Be radioactive-isotope (RI) beam at 3.16
MeV/u was produced at Center-for-Nuclear-Study RI Beam (CRIB) separator. The Q-value spectra shows the evidence of the three-body channels of interest. We confirmedthat the THM was applicable to the present measurements by the momentum distributions of the spectator proton. Preliminary excitation functions are roughly consistent with the previous studies, moreover providing new data in the BBN energy range, and suggesting that new information about the 7Be(n, p1)7Li* contribution may be obtained by carrying out a further data analysis. }

A type of measurement to study astophysical reactions at CRIB is by the elast$\alpha$,$\gamma$ resonant scattering with the thick-target method in inverse kinematics. An example is the α resonant scattering with 7Be beam, related to the astrophysical 7Be($\alpha$,$\gamma$) reactions, which is relevant in the hot p-p chain and $\nu$p-process in supernovae. Other α resonant scattering measurements with 30S, 10Be, 15O, and 18Ne beams have been performed at CRIB, using the thick-target method. There have also been measurements based on other experimental methods. The first Trojan horse method (THM) measurement using an RI beam has been performed at CRIB, to study the 18F(p, $\alpha$)15O reaction at astrophysical energies via the three body reaction 2H(18F, $\alpha$15O)n. The 18F(p, $\alpha$)15O reaction rate is crucial to understand the 511-keV $\gamam$-ray production in nova explosion phenomena, and we successfully evaluated the reactio cross section at novae temperature and below experimentally for the first time. }

The experimental data were analyzed within the framework of the optical model in order to extract the total reaction cross section. The comparison with data available in literature for reactions induced on 208Pb by light ions in the mass range A = 6-8 shows that the loosely-bound 8B has the largest reactivity.}

abstract = {{The $^{12}$C ({$\alpha$},{$\gamma$})$^{16}$O reaction at energies
corresponding to the quiescent helium burning in massive stars is
regarded as one of the most important processes in nuclear astrophysics.
Although this process has being studied for over four decades, our
knowledge of its cross section at the energies of interest for
astrophysics is still widely unsatisfactory. Indeed, no experimental
data are available around 300 keV and in the energy region of
astrophysical interest extrapolations are performed using some
theoretical approaches, usually R-matrix calculations. Consequently, the
published astrophysical factors range from 1 to 288 keVb for
S$_{E1}$(300) and 7 to 120 keVb for S$_{E2}$(300),
especially because of the unknown contribution coming from subthreshold
resonances. To improve the reliability of these extrapolations, data
from complementary experiments, such as elastic and quasi-elastic
{$\alpha$} scattering on $^{12}$C , {$\alpha$}-transfer reactions to
$^{16}$O , and $^{16}$N decay are usually included in the
analysis. Here the {$\beta$}-delayed {$\alpha$} decay of $^{16}$N is
used to infer information on the $^{12}$C
({$\alpha$},{$\gamma$})$^{16}$O reaction and a new experimental
technique is suggested.

Therefore, accurate thermonuclear reaction rates for (p,$\gamma$) reactions on the rp process path are essential for an understanding of the nucleosynthesis processes and energy production. We studied proton resonant states in $^{26}$Si and $^{27}$P via elastic scattering in inverse kinematics at the low-energy RI beam facility CRIB (CNS Radioactive Ion Beam separator), University of Tokyo. By using a thick H$_{2}$ gas target, excitation energies range of 6.8 to 8.2 MeV in $^{26}$Si and 2.3 to 3.8 MeV in $^{27}$P were scanned, respectively. Several resonances above the proton threshold level were observed with high statistics and free from any background contribution in the target. Their resonance parameters were subsequently extracted by an R-matrix analysis; these are important to better constrain the production rates of the $^{25}$Al(p,$\gamma$)$^{26}$Si and $^{26}$Si(p,$\gamma$)$^{27}$P reactions.},

abstract = {The $^{30}$S($\alpha$,\,p) reaction is considered to be important in the nuclear trajectory to higher mass in type I X-ray bursts. The reaction flow encounters a bottle-neck at $^{30}$S, owing to the competition of photo-disintegration with further proton capture, and because the half-life of this isotope is on the order of the burst rise timescale. Different burst simulations by various researchers indicate the ($\alpha$,\,p) reaction may by-pass this waiting point, depending on the stellar reaction rate, which has not previously been measured experimentally, and the structure of the compound nucleus $^{34}$Ar is not well understood above the alpha-threshold. The $^{30}$S($\alpha$,\,p) reaction could explain rare bolometrically double-peaked burst profiles, appears to make a considerable contribution to the overall energy generation, and affects the neutron star crustal composition for the recurrent inertia required in burst models to reproduce astronomical observations. Using a low-energy $^{30}$S radioactive ion beam and an active target technique (a helium gas mixture serves as both a target gas and a detector fill gas), we acquired data on both alpha elastic scattering of $^{30}$S as well as the $^{30}$S($\alpha$,\,p) reaction simultaneously at relevant energies for X-ray bursts. We present for the first time the status of the data analysis and the preliminary results of this research.},

An 89 MeV $^{21}$Na radioactive beam was produced by CRIB and then bombarded a 93-$\mu$m-thick polyethylene target. The $^{21}$Na beam intensity was about 2$\times$10$^{5}$ pps, with a purity of about 70\% on the target. The recoiled protons were measured by three sets of $\Delta$E-E telescope respectively. A wide excitation energy range of 5.5-9.2 MeV in $^{22}$Mg was scanned with a thick-target method. Some preliminary results are shown.},

We produce the radioactive ion $^{30}$S via the $^{3}$He($^{28}$Si,$^{30}$S)n reaction, by bombarding a cryogenically cooled target of $^{3}$He at 400 Torr and 80 K with $^{28}$Si beams of 6.9 and 7.54 MeV/u.

Based on our recent beam development experiments in 2006 and 2008, it is believed that such a beam may be fabricated in 2009 according to the results presented.

Research opportunities in the future at RIBF, J-PARC, and SPRING8 are also discussed. A discussion on the research activities at CNS has been specifically extended in the latter half, including various possibilities in collaboration at the RI beam factory at RIKEN. }},

The properties of these resonance states are important to better determine the production rates of $^{26}$Si(p,$\gamma$)$^{27}$P reaction which is one of the atrophysically important reactions to understand the production of the ground state of $^{26}$Al under the explosive stellar environments at higher temperature. In this work, some new states have been observed with a high statistics and background free through a covered the range of excitation energies from Ex = 2.3 to 3.8 MeV. The resonant parameters of those states, were determined by an R-matrix analysis of the excitation functions.},

abstract = {Nucleosynthesis of $^{22}$Na is an interesting subject because of possible {$\gamma$}-ray observation and isotopic anomalies in presolar grain. $^{22}$Na would have been mainly produced in the NeNa cycle. At high temperature conditions, $^{21}$Na({$\alpha$},p)$^{24}$Mg reaction could play a significant role to make flow from the NeNa cycle to the next MgAl cycle and beyond. Clearly, the $^{21}$Na({$\alpha$},p)$^{24}$Mg stellar reaction would bypass $^{22}$Na, resulting in reduction of $^{22}$Na production, therefore, it is strongly coupled to the Ne-E problem. It could be also important to understand the early stage of the rp-process. Experiment was performed using a 39 MeV $^{21}$Na radioactive beam obtained by the CNS Radio Isotope Beam separator CRIB of the University of Tokyo. Both protons and alphas were measured from {$\alpha$}+$^{21}$Na scattering with a thick $^{4}$He gas target.},

abstract = {The $^{14}$O($\alpha$, p)$^{17}$F stellar reaction is one of the key reactions for the breakout from the Hot--CNO cycle to the rp--process. Since the cross sections depends on the product of $\alpha$ and proton widths of the intermediate states in $^{18}$Ne, it is important to determine these widths. We performed an experiment of the $^{14}$O + $\alpha$ scattering with a thick target method at the CNS Radioactive Ion Beam (CRIB) facility. The experiment was carried out using a thick Helium gas target and position sensitive silicon telescopes. This measurement provides an excitation function of $^{14}$O + $\alpha$ scattering for an energy range of E$_{cm}$ = 1.7 -- 5.9 MeV. We will concentrate on the elastic scattering channel in this presentation, since the $\alpha$-cluster structure in $^{18}$Ne above the $\alpha$--threshold would play an important role for the stellar reaction. Several $\alpha$--resonances were observed in the present experiment. The experimental result will be presented, and the $\alpha$ cluster structure in $^{18}$Ne and the significance to the stellar reaction will be discussed.},

However, there are only very limited experimental information of the reaction cross section available from the time-reverse reaction studies. In order to determine the reaction rate of $^{11}$C($\alpha$,p)$^{14}$N, a direct measurement by means of the thick-target inverse-kinematics method has recently been performed using low-energy $^{11}$C beams from the CNS Radioactive Ion Beam (CRIB) separator, a $^{4}$He gas target and $\delta$E-E position-sensitive silicon telescopes at three downstream angles. The experiment covered E$_{CM}$ = 0.5--5 MeV corresponding to the stellar temperature of 1.5--7 GK. The obtained reaction cross section including some resonances and transitions to the excited states of $^{14}$N will be reported.},

abstract = {For the rapid proton capture process (rp-process) in X-ray bursts and the core-collapse stage of supernovae, proton-rich pf-shell nuclei far from the line of stability play important roles. Studies of the feeding ratios and half-lives of the $\beta$ and electron capture decays of these proton-rich pf-shell nuclei are of great astrophysical interest not only for nucleo synthesis but also for Fermi and Gamow-Teller transition study. The experiment to measure the half life of $\beta$ decay of $^{46}$Cr was performed using the low-energy RI beam separator (CRIB) of the Center for Nuclear Study (CNS), University of Tokyo. The $^{46}$Cr particles were produced by the $^{36}$Ar + $^{12}$C fusion reaction. A natural C foil of 0.56 mg/cm$^{2}$ was installed as the primary target. The $^{36}$Ar primary beam was accelerated up to 3.6 MeV/nucleon by the RIKEN AVF cyclotron. A double sided Si strip detector (DSSD) of 500-$\mu$m thickness was used as a $\beta$-ray detector. A Si detector of 1.5-mm thickness was placed just behind the DSSD for a $\beta$-ray detector. To measure $\beta$-delayed $\gamma$ rays, 3 clover and 1 coaxial Ge detectors were set around the target chamber. The beam was pulsed to measure the half life of the $\beta$ decay of $^{46}$Cr. The $\beta$-delayed $\gamma$ ray of $^{46}$Cr was observed in this experiment. The experimental result will be discussed.},
