Abstract
The excited states of the $\ensuremath{\mathsf{^{83}Rb}}$ nucleus were investigated in radioactive decay of $\ensuremath{\mathsf{^{83}Sr}}$ . The level scheme was established and for a number of levels spin-parity assignments are suggested on the basis of $\log ft$ values and $\gamma$ -branching ratios. Combining with the high-spin states observed by the in-beam $\gamma$ -ray spectroscopy of a previous decay work, the structure of the excited states of $\ensuremath{\mathsf{^{83}Rb}}$ is discussed in the framework of the projected shell model.
