摘要：

KEK Isotope Separation System (KISS) has been developed at RIKEN to produce neutron rich isotopes with N = 126 to study the beta-decay properties for application to astrophysics. The KISS is an element-selective mass-separation system which consists of an argon gas cell-based on laser ion source for atomic number selection and an ISOL mass-separation system. The argon gas cell of KISS is a key component to stop and collect the unstable nuclei produced in a multi-nucleon transfer reaction, where the isotopes of interest will be selectively ionized using laser resonance ionization. We have performed off- and on-line experiments to study the basic properties of the gas cell as well as of the KISS. We successfully extracted the laser-ionized stable Fe-56 (direct implantation of a Fe-56 beam into the gas cell) atoms and Pt-198 (emitted from the Pt-198 target by elastic scattering with a Xe-136 beam) atoms from the KISS during the commissioning on-line experiments. We furthermore extracted laser-ionized unstable Pt-199 atoms and confirmed that the measured half-life was in good agreement with the reported value. (C) 2016 Elsevier B.V. All rights reserved.
