Abstract

Heavy neutron-rich nuclei were populated via the fragmentation of a E/A=1 GeV 208 82Pb beam. Secondary fragments were separated and identified and subsequently implanted in a passive stopper. By the detection of delayed γ rays, isomeric decays associated with these nuclei have been identified. A total of 49 isomers were detected, with the majority of them observed for the first time. The newly discovered isomers are in 204,205 80Hg, 201,202,204,205 79Au, 197,203,204 78Pt, 195,199−203 77Ir, 193,197−199 76Os, 196 75Re, 190,191 74W, and 189 73Ta. Possible level schemes are constructed and the structure of the nuclei discussed. To aid the interpretation, shell-model as well as BCS calculations were performed.
