Description
The KEK Wako Nuclear Science Center (WNSC) has developed the KEK Isotope Separation System (KISS) at RIKEN to study the nuclear properties such as half-lives and atomic masses of the nuclei in the vicinity of neutron magic number N = 126, trans-uranium elements, and actinides. This research aims to explore the origin of heavy elements synthesized by the rapid neutron capture process.
The multinucleon transfer (MNT) reactions combined with a gas cell system enable us to produce these nuclei, which are difficult to study in other facilities. At the KISS facility, these neutron-rich nuclei have been produced by MNT reactions of 136Xe/238U beams and the production targets of W, Ir, and Pt. Their nuclear spectroscopy, including decay studies at a beta-gamma decay station, precise mass measurements using MRTOF-MS, and laser spectroscopy have been successfully performed.
To further this research, WNSC have started the construction of KISS-1.5 drastically to increase the experimental efficacy for nuclear spectroscopy.
In the talk, we will introduce the KISS facility, report the recent experimental results, and discuss future perspectives at KISS-1.5.
