Abstract [en]
High spin states in Cs-133 nucleus have been studied with the reaction Te-130 (Li-7, 4n) at a beam energy of 38 MeV. The level scheme has been expanded with spin up to 31/2 (h) over bar. Compared with a recent paper, ground state band and other two collective band structures at lower spin states have been confirmed. Another collective band structure at higher spin states as well as some levels and transitions are updated. Compared with the experimental data, large-scale shell model and tilted axis cranking model calculations have been carried out. The results show that the band-head configuration of yrast band based on 7/2(+) ground state and the side band built on the 5/2(+) state are a pair of pseudospin partner states with pi (f) over tilde 7/2,5/2. The negative parity band based on 1071.5 keV level originates from pi h(11/2) orbital. Another band built on 2642.9 keV level at high spin states has been proposed with oblate deformation. Other characteristics for these bands were also discussed.
