Non-collective oblate states in119Te

Abstract

High spin states of 119Te, populated in lJ~ 4n) and 11~ 3n) reactions, have been studied through y-ray spectroscopy. The level scheme has been established up to J~ = (55/2-). Three-quasiparticle states, based on :rgZ/z@vhaa/2 and 7zgT/zd5/2@vh11/2 configurations, have been identified. A particularly favoured 39/2-state is suggested to be the fully aligned 2 3 [7~g7/216 + @ [vhl 1/2127/2 -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-, 23/2and 37/2-.
