17. Overview of the experiment RIBF30 ; In-beam gamma-ray spectroscopy for vicinity of 78Ni

Shiga Yoshiaki (Rikkyo)

This experiment was performed at RIBF in 2011. The physical goal of this experiment is understanding nuclear structure and nuclear force in the region of around 78Ni. Excited energy levels of nuclei around 78Ni was studied by knock-out reaction impinging RI-beam on Be target(1889 mg/cm2). The gamma-ray was mesured by DALI2 at F8 detector and residual nuclei was identified by ZeroDegree...

7. In-beam gamma-ray spectroscopy next to 78Ni: the nuclei 77,79Cu (Status report for data analysis of RIBF30 experiment)

The question of the shell closure stability near the neutron drip-line has been in the forefront of the nuclear structure research for a long time. The next major neutron shell closure occurs at N=50, which is investigated in the vicinity of the possible doubly magic 78Ni. The doubly magic nature of 78Ni depends on the strength of the N=50 and Z=28 shell closures. The shell closures can be...

6. Neutron momopole drift towards 78Ni

We would like to present about our current investigation on neutron momopole drift towards 78Ni by performing gamma-ray spectroscopies in the odd-mass N=49 isotone; 79Zn. The study of single-particle levels in 79Zn will provide critical data to understand the neutron monopole evolution in the vicinity of 78Ni. Some of excited levels in 79Zn were identified by a β-γ spectroscopy performed as a...
