Properties of excited states in Ge77

The nucleus Ge-77 was studied through the Ge-76(C-13,C-12)Ge-77 reaction at a sub-Coulomb energy. The angular distributions of gamma rays depopulating excited states in Ge-77 were measured in order to constrain spin and parity assignments. Some of these assignments are of use in connection with neutrinoless double beta decay, where the population of states near the Fermi surface of Ge-76 was recently explored using transfer reactions.
