Abstract
Abstract The β + decay of 79 Rb has been studied with Ge(Li) detectors in singles and coincidence modes. The half-life of the 147.06 keV level in 79 Kr has been determined to be 78 ± 6 nsec. The relative electron intensities of seventeen transitions have been measured with a Si(Li) spectrometer. The internal conversion coefficients have been determined and the transition multipolarities have been deduced. Spin-parity assignments have been made for excited states of 79 Kr and the β + decaying ground state of 79 Rb ( 5 2 + ) . A Coriolis-coupling calculation using the Woods-Saxon potential together with a residual pairing and spin-spin interaction has been made. This model predicts the ground-state spin and parity of 79 Rb nucleus as well as the occurence and behaviour of most of 79 Kr states.
