Abstract

High spin states of121Te, populated in the114Cd(11B,p3n) reaction, have been studied throughγ-ray spectroscopy. The level scheme has been established up toJπ=51/2−. Three-quasiparticle states, based on the πg7/22⊗νh11/2 andπg7/2d5/2⊗νh11/2 configurations, have been identified. A favoured 39/2− state is suggested to be the fully aligned [πg7/22]6+⊗[νh11/2327/2− yrast non-collective oblate configuration. This assignment is supported by Total Routhian Surface (TRS) calculations which also suggest a similar oblate assignment to the states atJπ=21/2− and 23/2−. A higher 47/2− state is also found and is suggested to be the fully aligned [πg7/22]6+⊗[νh11/25]35/2− configuration.
