Abstract

Using on-line mass separation of evaporation residues from heavy-ion-induced fusion reactions, three new isotopes were identified by their alpha decay, Eα given in keV: 183Pb, 6715(20), 184Pb, 6632(10) and 188Bi, 6820(20). Half-lives were determined for 184Pb, 0.55(6)s, 185Pb, 4.1(3)s and 183Tl, 0.060(15) s. The alpha branching ratios were re-measured for 182–184Hg and 178, 179Pt, the results are discussed within the framework of alpha width systematics.
