Abstract

The collective structures of Ge75 have been studied for the first time via the Ge74(α,2p1n)Ge75 fusion-evaporation reaction. Two negative-parity bands and one tentative positive-parity band built on the νp1/2,νf5/2, and νg9/2 states, respectively, are established and compared with the structures in the neighboring N=43 isotones. According to the configuration-constrained potential-energy surface calculations, a shape transition from oblate to prolate along the isotopic chain in odd-A Ge isotopes is suggested to occur at Ge75. The properties of the bands in Ge75 are analyzed in comparison with the triaxial particle rotor model calculations.
