Abstract
The [Formula Presented] nucleus has been studied with the [Formula Presented] ([Formula Presented]) reaction at 240-MeV incident energy, extending the systematics of odd-[Formula Presented] isotones to higher [Formula Presented] For the yrast band, excited states up to a spin of [Formula Presented] have been observed. The first allowed backbend occurs at a rotational frequency of [Formula Presented] Three- and five-quasiparticle structures were identified, similar to those seen in lower mass [Formula Presented] isotones. Two of these structures have characteristics typical of mixed proton-neutron oblate configurations with one pair of aligned [Formula Presented] neutrons. In addition, two bands consisting of stretched [Formula Presented] transitions have been observed with no known analogous structures in neighboring nuclei. The results are discussed in terms of the cranking model. © 1999 The American Physical Society.
