Abstract: High-spin states in 179Au have been studied experimentally using the 149Sm(35Cl,5n) heavy-ion fusion-evaporation reaction at beam energies of 164—180MeV. Measurements of γ-ray excitation functions, X-γ coincidences and γ-γ-t coincidences were performed with 13 BGO(AC)HPGe and 3 LOAX detectors. Based on these measurements, a rotational band built on the 1/2[660](πi13/2) Nilsson state has been established for the first time, and this band has been assigned to 179Au according to the systematic of level structure in odd-A Au nuclei. Properties of the 1/2[660](πi13/2) band in odd-A Au nuclei are discussed with an emphasis on the band-head energy while changing the neutron number.
