抄録

The production and decay of 277112 have been investigated using a gas-filled recoil ion separator in irradiations of 208Pb targets with a 70Zn beam at 349.5 MeV. We have observed two α-decay chains that can be assigned to subsequent decays from 277112 produced in the 208Pb(70Zn,n) reaction. After emitting four consecutive α-particles, both the chains terminate by spontaneous fission decays of 261Rf, and the decay energies and decay times of both the chains obtained in the present work agree well with those reported by a group at Gesellschaft für Schwerionenforschung (GSI), Germany. The present result gives the first clear confirmation of the discovery of 277112 and its α-decay product 273Ds reported previously.
