Abstract

The structure of the very neutron-deficient Ge region has been investigated with use of particle-γ coincidence techniques in weak fusion-evaporation channels. Excited states up to spin (31/2) have been established in ${}^{65}{Ge}$ , and five transitions have been assigned to the N=Z nucleus ${}^{64}{Ge}$ . The first excited state in ${}^{64}{Ge}$ is at 902.1±0.8 keV. The ${}^{65}{Ge}$ level scheme provides the first indication in this mass region of a theoretically predicted softness with respect to octupole deformation.
