Abstract
The fragmentation of relativistic uranium projectiles has been exploited at the Gesellschaft für Schwerionenforschung laboratory to investigate the decay of neutron-rich nuclei just beyond Pb. This paper reports on -delayed decays of Tl, Pb, and Bi de-exciting states in the daughters Pb, Bi, and Po. The resulting partial level schemes, proposed with the help of systematics and shell-model calculations, are presented. The role of allowed Gamow-Teller and first-forbidden transitions in this mass region is discussed.
