Abstract

High-spin states in Ce-133 were populated via the Cd-116(Ne-22,5n) reaction at 120 MeV. Analysis of these data has revealed three new superdeformed bands in Ce-133, two of which have transitions which are identical to those observed in the yrast bands of Ce-132 and Nd-136. These bands have been interpreted as signature partners of the [530] 1/2(-) orbital coupled to the Ce-132 yrast superdeformed core. The third band is believed to be built upon a pi 5(4) nu 6(3) configuration at high rotational frequency and to show the effects resulting from an alignment of a pair of f(7/2) neutrons at ($) over bar h omega similar or equal to 0.7 MeV. It is tentatively suggested that the sharp rise in the dynamic moment of inertia of this band at low rotational frequency may result from an admixture of the pi 5(4) nu 6(1) configuration.
