Research theme
- Nuclear structure far from the stability
- SHARAQ Project
Research
Studying various properties of exotic nuclei, which have different ratios of neutrons to protons from those of stable nuclei, by using nuclear reactions with secondary beams of exotic nuclei. Wave functions of loosely bound nucleons, change of magic numbers, exotic excitation modes, and reaction mechanisms are studied by utilizing suitable selectabilities of nuclear reactions by changing incident energies and targets.

Research
Study of high-spin states in unstable nuclei by using RI beam. Experiments are usually made using RIKEN Projectile Fragment Separator (RIPS) and CNS Ge detector array (GRAPE). By using RIPS, we produce neutron-rich as well as proton-rich RI beams and decelerate them down to 5MeV/A in order to induce low-energy secondary reaction, such as fusion, Coulomb excitation, direct reaction, etc. By utilizing low-energy RI beams in the secondary reactions and gamma-ray spectroscopy, we aim for clarifying nuclear structure as a function of spin and isospin. Especially, we have much interest in the study of extremely deformed nuclear shapes.

Research theme
- In-beam gamma spectoscopy of neutron rich nuclei
  - Spectroscopy of 13B via 4H(12Be,13B)X reaction
  - Spectroscopy of the neutron-rich nuclei in N=20 region via alpha induced reaction in inverse kinematics
- Gamow-Teller strengh distribution
Research
Experimental study on the evolution of the shell structure in the exotic unstable nuclei. The shell structure dynamically changes not only by added one nucleon to the nucleus, but also by exciting one nucleon in the nucleus. We aim at searching such a changing of shell structure in the nuclei, in particular nearby shell closure, and clarifying its property.
