Abstract:	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 126 and 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 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.
