Abstract： We perform a series of theoretical calculations and investigation for nuclei 179,181,183Au in the
particle--triaxial-rotor model with variable moment of inertia. The calculated energy spectra in 179,181,183Au agree well with the experimental data globally. The obtained results indicate that the nuclei 179,181,183Au have prolate deformation and involve shape coexistence with different deformation parameters in different bands. The main configuration of bands 1, 2, 3 and 5 in these nuclei are identified as [541]1/2- (π h9/2, α=1/2), [541]1/2- (π h9/2, α=-1/2), [530]1/2- (π f7/2) and [660]1/2+ (π i13/2), respectively.
