Abstract
Through study of the prompt gamma -rays emitted in the spontaneous fission of Cf-252, high spin states of neutron-rich odd-A Ce-145,Ce-147 nuclei have been investigated. The levels in Ce-147 have been extended. A collective b and in Ce-145 have been identified for the first time. The results from the par tide rotor model calculations indicate that the yrast bands in 145Ce a nd 147Ce originate from nui(13/2) orbital coupling and the ground states of Ce-145 and Ce-147 originate from (Vh(9/2)circle times nuf(7/2)) and vh(9/2 ) configuration, respectively. No obvious octupole deformation was observed in these two isotopes, but a side band obtained in Ce-147 may show some oc tupole correlations.
