Abstract

The gamma rays and conversion electrons emitted in the beta decay of Sr-78 to levels in Rb-78 have been studied using Ge detectors and a mini-orange spectrometer. A reliable level scheme based on the results of these experiments has been established. The properties of the levels in Rb-78 have been compared with calculations based on deformed Hartree-Fock with Skyrme interactions and pairing correlations in the BCS approximation. This has allowed an interpretation of the nature of the observed sets of levels in the odd-odd nucleus Rb-78.
