Abstract

We study ground states and β-decay properties of the proton rich isotope chains Ge, Se, Kr, and Sr. We use a deformed selfconsistent HF+RPA approach with density-dependent effective interactions of Skyrme type. We find that most of the isotopes present two HF minima corresponding to two different shapes. In addition to static quadrupole moments and other ground state band properties, we present results for Gamow Teller strength distributions, as well as for half-lives and summed strengths. The role of deformation is particularly emphasized.

      The idea, first introduced by I. Hamamoto and coworkers [10] and later developed by P. Sarriguren et al. [11], is based on the dependence of the β strength of the decay on the nuclear shape assumed for the parent state. Information on the deformation of the ground state of the decaying nucleus can be obtained from the comparison between experiment and theory in cases where the pattern of the theoretical strength distributions shows a clear dependence on the shape [12–16]. For a proper determination of the experimental β strength, these studies require the application of the total absorption gamma spectroscopy (TAGS) technique, that provides β-decay data free from the Pandemonium systematic error [17].
