A new rotational band has been identified and assigned to
188
Au for the first time using the
173
Yb(
19
F,4n
γ
) reaction at the beam energies of 86 and 90 MeV. This band is proposed to be built on the
πh
9/2
⊗
νi
13/2
configuration by comparing the band properties with known bands in neighboring nuclei. The prolate-to-oblate shape transition through triaxial shape has been proposed to occur around
188
Au for the
ηh
9/2
⊗
νi
13/2
bands in odd-odd Au isotopes on the basis of total Routhian surface (TRS) calculations.
