原子核科学研究センターは1997年に東京大学における原子核科学の研究および教育の推進のため、大学院理学系研究科附属の施設として発足しました。本センターの前身は、物質の究極の構成要素をさぐる大型研究の日本における草分けとなった東京大学原子核研究所です。その開拓の精神を受け継いで、重イオンをキーワードとして、物質のなりたちの謎を探り、明らかにすることを目指した研究を進めています。また、イオンビームや放射線検出器の応用分野への展開もはかっています。
本センターの本部は本郷キャンパスにありますが、研究活動の多くは埼玉県和光市にある理化学研究所の和光キャンパス内にある支所で行われています。理化学研究所の仁科加速器センターとの密接な連携を柱に、国際的な共同研究を推進し、独自の視点から原子核物理学を軸にした研究を進め、世界を先導する成果を出しています。
東京大学大学院理学系研究科物理学専攻の協力講座として、毎年新たな大学院学生を受け入れ、修士号や博士号を持った人材を送り出しています。海外の先端的な研究施設との共同研究やそれに伴う教育活動も盛んに行われています。学部教育として教養学部や理学部に協力し、体験ゼミナールや学生実験など、研究現場での実機を用いたユニークな教育を実施しています。
本センターの研究活動は、大学院学生や博士研究員を含む若手の方々の活躍に支えられています。重イオンに関わる科学研究や開発、勉学に意欲のある方を心から歓迎しています。

Nuclear Astrophysics - Exploring the Cosmos
CNS RI beam separator – CRIB is maintained and operated by the Nuclear Astrophysics Group in Center for Nuclear Study, University of Tokyo. CRIB, producing low-energy and high-intensity RI beam by direct reactions, is a unique apparatus, one could hardly find a similar one even in the facilities all over the world. Making use of the uniqueness of CRIB, we are extensively studying the following topics:
-
Direct/indirect measurements of important reactions in nuclear astrophysics.
Using the low-energy, low-mass and proton-rich beams at CRIB, a systematic study has been made for the nucleosynthesis of proton-rich region. We aim to understand the nucleosynthesis in a high-temperature phenomena such as supernovae, and production of p-nuclei. -
Studying nuclear resonance structure by resonant scattering method.
We are interested in studying exotic nucluar structure, such as proton halo and alpha cluster. We use a special method to observe nuclear resonances, and derive information on the nuclear structure.
Dynamics of Nuclear Quantum System
Nuclear structure of neutron-rich nuclei which will be produced by RIPS or BigRIPS at RIBF are to be studied by employing the low-energy nuclear reactions such as proton resonance elastic scattering. In particular, the nuclei around 32Mg where the nuclear structure suddenly changes are being studied. This experiment can be related to an unknown nuclear force which breaks the isospin symmetry.
In paralle with the studies, we are developing devices to produce a high spin isomer target of 178m2Hf, which will be synthesized, and then purified by using the laser resonant ionization. When it is succeeded, long-standing dream of nuclear physics, production of hyper deformation, torus shape of nucleus, would come true.
FundamentalSymmetry
To explore the mechanism responsible for the generation of observed matter-antimatter asymmetry in the Universe, the research on fundamental symmetry violations and various fundamental interactions using the laser cooled and trapped heavy elements is being promoted. The understanding of how the symmetry between the matter and antimatter was broken during the evolution of the early universe requires laboratory experiments which search for symmetry violations in the elementary particles such as quarks and leptons; one such phenomenon of our interest is the intrinsic electric dipole moment (EDM) of either elementary or composite systems. In our laboratory, we produce extremely heavy radioactive elements from nuclear fusion reactions. We trap the heavy unstable atoms and cool them using intense laser beams in order to realize the extreme quantum state of matter such as the Bose-Einstein condensate (BEC), which will be used later for the detection of the EDM signal. The construction of a facility containing high density of laser cooled radioactive atoms is in progress, and it serves as a center for carrying out several studies on fundamental symmetries.
Nuclear Spectroscopy for Extreme Quantum System (NUSPEQ)
We are studying variety and regularity in nuclear system under various extreme conditions, such as neutron-/proton-rich nuclei, rapidly rotating nuclei, highly excited nuclei, and so on, by using characteristic nuclear reactions and measurements of decay particles.
We aim at microscopic understandings of synthesis and evolution of matter via symmetries, their breakings, and recovering modes appearing in the quantum many-body system of two kinds of fermions, the proton and the neutrons.
We are developing posistion sensitive Ge detector array GRAPE and promoting SHARAQ projects.

Quark Physics
The quark physics group has been participating the PHENIX experiment at RHIC in Brookhaven National Laboratory, USA, and the ALICE experiment at LHC in CERN, Europe, and our main goals are to find evidence of quark gluon plasma (QGP), which is a new form of matter with deconfined quarks and gluons, and to study its properties. QGP is stable under extreme high temperature of more than one trillion degrees, and is a primitive form of matter considered to exist in a few micro-seconds after the Big Bang.
Exotic Nuclear Reaction
The components of nucleus, neutron and proton, have their spins and isospins and their combination leads to various aspects of nucleus. Nuclear structure has been studied by manipulating these quantum numbers as well as the internal energy of nuclei by scattering and other experiments. RI beams provides us of a new means of manipulation while RI beams themselves are of keen interest. We are exploring new aspects of nucleus by using the high-resolution magnetic spectrometer SHARAQ, the active target system, and other apparatuses.
SHARAQ Project
“Mass”-production of unstable nucleus enhance the possibility of new scientific research. We have constructed the high-resolution SHARAQ spectrometer for pioneering new physics researches with radioactive nuclear beams. SHARAQ can analyze energies of radioactive nuclear beams or their reaction products with an energy resolution as high as 1/7500. The SHARAQ*1 has been commissioned in March 2009 and are being improved day by day.
Heavy-Ion Accelerator Technology
Heavy ion beams provide a wide range of experimental applications to nuclear physics as well as other sciences and technologies. CNS has been devoting in development of ion-source technology for heavy ions and AVF cyclotron technology in collaboration with RIKEN. In practice, CNS ion sources are providing all heavy ion beams for the RIKEN AVF cyclotron for a variety of nuclear sciences including nuclear physics, bioscience and material science.
