Abstract：
High-spin states in ^179,183Au have been studied experimentally using the ¹⁴⁹Sm(³⁵Cl,5n)¹⁷⁹Au and ¹⁵⁹Tb(²⁹Si,5n)¹⁸³Au heavy-ion reactions, respectively. The 1/2[660](πi_13/2) rotational band has been established for the fist time in ¹⁷⁹Au. A rotational band proposed as the unfavored signature branch of the πi_13/2 band has been newly observed in ¹⁸³Au. Properties of the 1/2[660](πi_13/2)band in odd-A Au nuclei are discussed with an emphasis on the evolution of deformation while changing the neutron number.
