High-spin states in 121,122Te: Identification of favored noncollective oblate states.

Abstract

High-spin states up to {ital I}{approximately}20{h_bar} have been studied in the {sup 121,122}Te nuclei using the {sup 116}Cd({sup 9}Be,{ital x}n) reaction at 37.8 MeV. In this spin regime, several favored noncollective oblate states ({gamma}=+60{degree}), where the single-particle angular momenta generate the total nuclear spin, are predicted to coexist with weakly deformed collective structures. Theoretical expectations for such oblate states, based on TRS cranking calculations, are compared to the experimental results. {copyright} {ital 1996 The American Physical Society.}
