We developed KEK Isotope Separation System (KISS) in RIKEN Nishina center to produce neutron-rich isotopes around N = 126 for the study of β-decay properties from astrophysical interests. The KISS is an argon-gas-cell-based on laser ion source with

We developed a multi-segmented proportional gas counter to perform β-decay spectroscopy of neutron-rich nuclei extracted from KEK Isotope Separation System (KISS). The 32 segmented gas counters allow us two-dimensional tracking of the events to iden

Deexcitation $\ensuremath{\gamma}$ rays associated with an isomeric state of the $^{195}\mathrm{Os}$ were measured for the first time. The half-life of the isomeric state of the neutral atom $^{195\mathrm{m}}\mathrm{Os}$ was deduced. The isomers were

We have developed a doughnut-shaped argon gas cell with a rotating target for the KEK Isotope Separation System (KISS). The new gas cell increased extraction yields for target-like fragments (TLFs) produced in multi-nucleon transfer (MNT) reactions.
