  We study ground states and beta 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.
