Abstract：
The low-energy and 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 log ft 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-tate 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 also shown in order to extract physics out of the numerical results.
