Low-spin states and level structure of odd-even rubidium isotope:83Rb

The low-spin part of the nucleus was investigated in radioactive decay of . The decay scheme was established and for a number of levels spin-parity assignments are suggested on the basis of logft values and γ-branching ratios. In order to discuss the band structures of this nucleus, the projected shell model is applied to the nucleus . The results of theoretical calculations about the excited positive-parity yrast states and the negative-parity ground-state band are compared with experimental data, and the best reproduction of the experiment has been given by this model. In addition, a band diagram calculated for the negative-parity g.s. band is used in order to extract physics out of the numerical results.
