At RIKEN Nishina Center, a series of experiments for studying the heaviest elements has been done by using a gas-filled recoil ion separator (GARIS). Isotopes of the 112th and the 113th elements, 277Cn and 278113 by the 70Zn induced one neutron emission reactions on the targets 208Pb and 209Bi, respectively. The former provided an independent confirmation of the production of an isotope, 277Cn, of the 112th element reported firstly by the GSI (Helmholtzzentrum für Schwerionenforschung GmbH, Germany) research group. The latter was the first observation of the 113th element produced by the 'cold fusion' reaction. A gas-jet transport system coupled to GARIS was successfully operated for the chemistry study of the heaviest elements.
