Shapes and beta-decay in proton rich Ge, Se, Kr and Sr isotopes

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...
