| 摘 要： | A standard in-beam γ-spectroscopy experiment for^179 Au 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 1/2[660](π^i13/2)proton intruder orbital is established for^179 Au for the first time. Systematic properties of the 1/2[660](π^i13/2) band in odd-A Au nuclei are discussed,and the evolution of bandhead energy and deformation with changing neutron number are revealed.
