Abstract： By taking the particle triaxial-rotor model with variable moment of inertia, we investigate the energy spectra, the deformation and the single particle configuration of the negative-parity states in nuclei 191,193,195,197Au systemically. The calculated energy spectra agree well with experimental data. The obtained results indicate that the negative-parity states in 191,193,195,197Au originate from the proton-hole h11/2 configuration coupled to a triaxial oblate Hg core. Meanwhile the main single particle configuration of the bands 1, 2 and 3 are identified to be |5h11/2 1/2 > (α= - 1/2), |5h11/2 > (α= 1/2) and |5h9/2 7/2>;, respectively.
