Collective shape degrees of freedom have been a major direction in the study of the nuclear finite many-body problem for over 50 years. There is widespread evidence for quadrupole deformations, primarily of large prolate spheroidal deformation with axially symmetric rotor degrees of freedom. This naturally leads to the question of whether axially asymmetric rotor degrees of freedom are...

In the past twenty years, great efforts have been devoted to chiral symmetry, from both theoretical and experimental sides. As the frontier of such researches, multiple chiral doublet bands (M$\chi$D) have been observed in several nuclei.

From an experiment performed in Legnaro, Italy, we found a level structure exhibiting multiple chiral doublet bands in $^{131}$Ba, which include 2... -

Nuclei with mass A <120 are perfectly placed to study the shape-driving properties of different quasiparticle configurations. For these nuclei, the Fermi surface for the protons lies close to the low-Ω h11/2 orbitals which drives the nucleus towards prolate shape, while the neutron fermi surface lies near the mid-Ω h$_{11/2}$ orbitals which induces an oblate deformation. Due to the conflicting...

Recently the DESPEC nuclear spectroscopy campaign started at the SIS18/FRS facility at GSI as part of the FAIR/NUSTAR Phase-0 program. It aims at the investigation of exotic heavy nuclei produced in fragmentation reactions employing detectors and instrumentation developed for the FAIR facility. With the unique availability of new lanthanide primary beams, i.e. $^{170}$Er, secondary ion beams...

The decay of the excited states of the atomic nucleus is almost always companied by gamma radiation. Large gamma detection platform, which could give the most important observables of the nucleus, is proved to be one of the essential instruments of the laboratories around the world. A new detector array consisting of 32 detection elements of the early phase, including 16 coaxial HPGe...

The Research Center for Nuclear Physics, Osaka University, is an accelerator facility with an AVF cyclotron and a ring cyclotron, which can be used for various nuclear physics research. To advance nuclear structure research by gamma-ray spectroscopy, we have initiated the CAGRA project, based on the international collaboration among Japan, the U.S., and China. CAGRA array consists of up to 16...
