Abstract
The beta decay of69As is reinvestigated. Its decay half-life is measured to be 15.1±0.3 m. Using beta, gamma and conversion electron spectroscopy techniques, a decay scheme comprising 68 transitions among 28 excited states in69Ge is proposed. Spin-parity assignments are made to many states andB(M1) andB(E2) are deduced for some transitions. The structure thus obtained for69Ge is compared with that from other works and discussed in the light of nuclear models.
