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

Document Type


Publication Date



The low-spin part of the 83Rb nucleus was investigated in radioactive decay of 83Sr. 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 83Rb. 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. © 2010 Elsevier B.V. All rights reserved.
