Phys. Rev. Lett. 72, 3150–3153 (1994)New features of superdeformed bands in 194HgReceived 17 November 1993; published in the issue dated 16 May 1994 Two new features of superdeformed (SD) bands in the A≊190 region emerge from a study of 194Hg with the Gammasphere detector array. A decrease of the dynamic moment of inertia is observed for rotational frequencies ħω≥0.4 MeV, confirming long standing expectations based on mean field calculations with pairing. Evidence for a small staggering in the SD transition energies is also observed, suggesting the presence of terms with fourfold symmetry in the SD Hamiltonian. © 1994 The American Physical Society URL:
