Decay of Sr-83 and level structure of Rb-83

The excited states of the Rb-83 nucleus were investigated in radioactive de cay of Sr-83. The level scheme was established for a number of levels spin- parity assignments are suggested on the basis of log ft values and gamma -b ranching ratios. Combining with the high-spin states observed by the in-bea m gamma -ray spectroscopy of a previous decay work, the structure of the ex cited states of Rb-83 is discussed in the framework,rk of the projected she ll model.
