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.
