Non-collective oblate states in119Te

Abstract

High spin states of119Te, populated in110Pd(13C, 4n) and110Pd(12C, 3n) reactions, have been studied throughγ-ray spectroscopy. The level scheme has been established up to jπ=(55/2−). Three-quasiparticle states, based onπg 7 2/2 ⊗vh 11/2 andπg 7/2 d 5/2⊗vh 11/2 configurations, have been identified. A particularly favoured 39/2− state is suggested to be the fully aligned [πg 7 2/2 ]6+⊗[vh 11 2/3 ]27/2− yrast non-collective oblate configuration. This assignment is supported by Total Routhian Surface (TRS) calculations which also suggest a similar oblate assignment to states at 21/2−, 23/2− and 37/2−.
