Abstract

We present the observation of an isomeric decay in the very neutron deficient nucleus Kr-74(36). The isomer is interpreted as an excited 0(+) state, consistent with the long standing prediction of high deformation prolate/ oblate shape coexistence in this nucleus. The magnitude of the EO matrix element deduced for the 0(2)(+) --> 0(1)(+) transition gives strong support to the prediction of a highly deformed oblate rotor.
