Abstract

The nucleus ⁷⁰Se was studied using the ⁴⁰Ca( ⁴⁰Ca, 2α2p) reaction at a beam energy of 185 MeV. Gamma rays were measured with the EUROBALL III spectrometer. The known positive-parity bands have been extended and one new band of positive parity and two of negative parity have been identified. These bands are interpreted in terms of the cranked Nilsson-Strutinsky approach. Calculations suggest that the two negative-parity bands, which have the same signature, are both based on a configuration with two protons and three neutrons lifted from the fp shell to the g_9/2 orbital, but at different nuclear shapes. This represents a shape coexistence at high spin.
