摘要

The KEK Isotope Separation System (KISS) at RIKEN has been successfully implemented to investigate nuclear structure of the nuclei in the vicinity of neutron magic number \(N=\) 126 and \(^{238}\) U from the astrophysical perspective. The KISS facility provides a low-energy (20 keV) ion beam for nuclear spectroscopy utilizing multinucleon transfer (MNT) reactions to produce neutron-rich nuclei in combination with an argon gas-cell system. These nuclei are re-ionized by applying in-gas-cell laser ionization technique, enabling laser ionization spectroscopy even for refractory elements with the atomic number \(Z=\) 70–78, which are inaccessible at other facilities. We have successfully reported the experimental results using in-gas-cell laser ionization with a limited laser resolution of about 10 GHz. To achieve significantly higher precision in laser spectroscopy, with a resolution of a few hundred MHz at KISS, we plan to install a CLARIS (Collinear LAser Resonance Ionization Spectroscopy) beamline.
