Levels ofKr83populated in the decay ofRb83andBr83

The levels of ${}_{}{}^{83}{}_{}{}^{}\mathrm{Kr}$ were studied from the decay of both ${}_{}{}^{83}{}_{}{}^{}\mathrm{Rb}$ and ${}_{}{}^{83}{}_{}{}^{}\mathrm{Br}$. Thirteen $\gamma$ rays were observed in the decay of ${}_{}{}^{83}{}_{}{}^{}\mathrm{Rb}$ and eight in the decay of ${}_{}{}^{83}{}_{}{}^{}\mathrm{Br}$. The ground-state $M2\mathrm{}$ transition from the 562-keV level was observed to have a branching ratio of 1.4 × ${10}^{-4\mathrm{}}$. The conversion coefficients were measured for the 9.39 keV and for the 32.2-keV transition. Decay schemes are presented and the possible spins, parities, and structure for the levels of ${}_{}{}^{83}{}_{}{}^{}\mathrm{Kr}$ are discussed.
