Abstract
The high-spin level structure of has been investigated via the (,) reaction at beam energies of 86 and 90 MeV. The previously reported level scheme has been modified and extended significantly. A new state associated with configuration and two new rotational bands, one of which is built on the configuration, have been identified. The prolate-to-oblate shape transition through triaxial shape has been proposed to occur around for the bands in odd-odd Au isotopes. Evidence for structure of nonaxial shape with has been obtained by comparison with total Routhian surface and cranked-shell-model calculations.
