Selected Topics on Nuclear Structure in Rare Electroweak Processes

Abstract

We analyze the active-shell occupation probabilities of 76 Ge and their contribution to the single-and double-beta decay matrix elements of this isotope. Strength modifications of the nucleon spin-orbit interaction are introduced for a better comparison with experimental data. The relation of this spin-orbit interaction with the nucleon densities is explored, and the latter are analyzed for 76 Ge in the context of parity-violating electron scattering as a tool to extract accurate experimental information on neutron distributions.
