Identification of Oblate Band in Odd-Odd 184Au

         

摘要

@@ High-spin states in 184Au have been populated via the 149Sm(29Si, 4nγ) 184Au reaction at a beam energy of140 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 πh11-1/2 vi13-1/2 structure has been newly observed, similar to those reported in 186-194Au. This result extends the knowledge of shape coexistence to the currently lightest odd-odd Au isotope.
