Abstract： A standard in-beam γ-spectroscopy experiment for 179Au has been performed via the 149Sm (35Cl, 5n) reaction at beam energies of 164-180 MeV. Based on the analysis of the experimental results, a rotational band built on the 1/2 [660](πi13/2) proton intruder orbital is established for 179Au for the first time. Systematic properties of the 1/2 [660](i13/2) band in odd-A Au nuclei are discussed, and the evolution of bandhead energy and deformation with changing neutron number are revealed.
