Abstract
Obtaining information of nuclear shape deformation and nuclear clustering far from the valley of stability is the long-sought goal in nuclear physics. With high intensity radioactive beams provided by RIKEN facility, such physics in very neutron-rich nuclei can be experimentally studied.
Shape deformation evolves with the increase of neutron number. One interesting case is Co isotopes because they reside between the spherical shaped nuclei (Ni) and the deformed ones (Fe). Also it is expected that Co isotopes show the coexistence of both spherical and deformed structures. Therefore we have measured the level structure of 69,71,73Co via in-beam gamma technique using DALI2 gamma-ray detection array at RIKEN facility. In this talk, the experimental set-up and results will be presented.
Another interesting structure in nucleus is alpha clustering. It is predicted that strong alpha cluster appears in neutron-rich Be isotopes. To observe this phenomena, we will perform quasi-free scattering (p,pα) experiment on 10,12,14Be isotopes using SAMURAI spectrometer at RIKEN. The experiment is under preparation. In this talk, we will present experimental set-up and preparation.
Anyone interested is welcome to attend.
