Abstract

Seven ²⁷¹Ds decay chains were identified in the bombardment of ²⁰⁸Pb targets with 311.5 and 314.3 MeV ⁶⁴Ni projectiles using the Berkeley Gas-filled Separator. These data, combined with previous results, provide an excitation function for this reaction. From these results, an optimum energy of 321 MeV was estimated for the production of ²⁷²111 in the new reaction ²⁰⁸Pb(⁶⁵Cu,n). One decay chain was observed, resulting in a cross section of 1.7_\ensuremath-1.4^+3.9 pb. This experiment confirms the discovery of element 111 by the Darmstadt Group who used the ²⁰⁹Bi(⁶⁴Ni,n)²⁷²111 reaction.
