• 論文の詳細を見る

• The production and decay of ^<272>111 has been investigated using a gas-filled recoil ion separator in irradiations of ^<209>Bi targets with ^<64>Ni 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 ^<272>111 produced in the ^<209>Bi(^<64>Ni,ln) reaction. The present result is the first clear confirmation for the discovery of ^<272>111 and its α-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.
