• The high-spin level structure of 186Au is re−investigated by means of in-beam γ−ray spectroscopy via the 172Yb(19F, 5nγ)186Au reaction. The oblate bands previously reported are revised and extended to higher−spin states. A new Iπ=(20+) excited state has been identified and assigned to the πh11/2−1 ⊗νi13/2-2h9/2-1 configuration. The total Routhian surface and cranked shell model calculations suggest that the πh11/2−1 ⊗νi13/2-2h9/2-1 band in 186Au has a non-axial deformation.
