Description

High angular momentum states in 195-197Bi are populated in two reactions: 183W(19F,xn)202-xBi and 181Ta(20Ne,xn)201-xBi at beam energies of 108 and 123 MeV, respectively. Gamma rays were detected using the Gammasphere array. Three weakly populated rotational sequences have been found. They each have properties characteristic of other superdeformed bands in this mass region. On the basis of cross-bombardment information we believe that one band belongs to each of 195Bi, 196Bi, and 197Bi. The properties of the bands in the odd-Bi nuclei are best reproduced if the odd proton occupies the favored signature of the [651]1/2 orbital, while the band in 196Bi has this same proton configuration coupled to an additional N=7 (j15/2) neutron. The relative behavior of the at sign F I(2) moments of inertia can be qualitatively understood in terms of Pauli-blocking effects. copyright 1996 The American Physical Society
