Abstract:
High-spin states in 183Au have been studied experimentally using heavy-ion-induced fusion-evaporation reaction and standard in-beam γ-ray spectroscopic techniques. The level scheme of 183Au was revised and extended. A rotational band proposed as the unfavored signature branch of the πi13/2 band has been observed for the first time. Interaction properties between the two negative-signature bands of the πh9/2-πf7/2 system have been discussed for the light odd-A Au nuclei.
