Abstract

A new superdeformed band is reported in Hg-193 which has properties that are consistent with it being based on the unfavoured N = 7 (pi, alpha) = (-, + 1/2) intruder orbital. The signature splitting at HBARomega = 200 keV of this intruder orbital and its favoured (-, - 1/2) partner is estimated to be 160 +/- 30 keV, which is in agreement with cranked mean field calculations. This band completes the set of low-lying quasi-neutron orbitals predicted to be at the N = 113 superdeformed Fermi-surface. The previously known superdeformed bands in Hg-193 have been extended to higher rotational frequencies, HBARomega greater-than-or-equal-to 0.40 MeV.
