Abstract
High-spin states in 184 Au have been populated via the 149 Sm( 29 Si, 4 n γ) 184 Au reaction at a beam energy of 140 MeV. Three- or higher-fold γ-ray coincidences have been measured using the multidetector array of GASP. A rotational band built on the 11 − oblate π h 11/2 −1 ⊗ν i 13/2 −1 structure has been newly observed, similar to those reported in 186−194 Au. This result extends the knowledge of shape coexistence to the currently lightest odd–odd Au isotope.
