Abstract

The production and decay of 272111 has been investigated using a gas-filled recoil ion separator in irradiations of 209Bi targets with 64Ni beam at 320, 323 and 326 MeV. We have observed 14 α-decay chains in total, that can be assigned, on the basis of their time correlations, to subsequent decays from 272111 produced in the 209Bi(64Ni,ln) reaction. The present result is the first clear confirmation for the discovery of 272111 and its α-decay products, 264Bh and 268Mt, reported previously by a GSI group. New information on their half-lives and decay energies as well as the excitation function is presented.
