Description
The high-spin states in 184Hg have been investigated via the 154Gd (32S,4n) reaction at a beam energy of 160 MeV, with an array of Compton suppressed Ge detectors in the Spin Spectrometer at HHIRF. The ground state oblate band and excited prolate band were extended to 10+ and 26+, respectively, and seven new bands are observed. A new band with odd spins, 13 to 25, has a much larger moment of inertia than the other bands in 184Hg. Two of the new bands feed the prolate excited band and are interpreted as quadrupole vibrational bands. Also, two new signature partner bands are observed for which the configuration of νi13/2f7/2 is proposed. The similarity of the band with odd spins to the band with intermediate deformation (β2∼0.34) in 186Hg, and signature partner bands to the bands observed in 104 isotones 180Os and 182Pt, is discussed
