Abstract

High spin states in 80Sr have been studied using the techniques of in-beam γ-ray spectroscpy. The ground state band has been investigated up to (26+) and three new side-bands have been discovered. The deduced level scheme is compared with cranking model calculations; the predicted transformation to mostly non-collective excitations of an oblate shape is not observed. The behaviour of the J(1) and J(2) moments of inertia is discussed and presented as evidence for γ-softness in the light Sr isotopes.
