Abstract

The high-spin level structure of Au188 has been investigated via the Yb173(F19,4nγ) reaction at beam energies of 86 and 90 MeV. The previously reported level scheme has been modified and extended significantly. A new Iπ=20⊃+ state associated with πh11/2-1-νi13/2-2h9/2-1 configuration and two new rotational bands, one of which is built on the πh _9/2-νi_13/2 configuration, have been identified. The prolate-to-oblate shape transition through triaxial shape has been proposed to occur around Au188 for the πh_9/2-νi_13/2 bands in odd-odd Au isotopes. Evidence for πh11/2-1-νi13/2-1 structure of nonaxial shape with γ<-70⊃°has been obtained by comparison with total Routhian surface and cranked-shell-model calculations.
