摘要：

The production and decay of (272)111 has been investigated using a gas-filled recoil ion separator in irradiations of Bi-209 targets with Ni-64 beam at 320, 323 and 326 MeV. We have observed 14 alpha-decay chains in total, that can be assigned, on the basis of their time correlations, to subsequent decays from (272)111 produced in the Bi-209(Ni-64, In) reaction. The present result is the first clear confirmation for the discovery of (272)111 and its alpha-decay products, (264)Bh and (268)Mt, reported previously by a GSI group. New information on their half-lives and decay energies as well as the excitation function is presented.
