Abstract
Two new features of superdeformed (SD) bands in the A almost-equal-to 190 region emerge from a study of Hg-194 with the Gammasphere detector array. A decrease of the dynamic moment of inertia is observed for ro tational frequencies HBARomega greater-than-or-equal-to 0.4 MeV, confi rming long standing expectations based on mean field calculations with pairing. Evidence for a small staggering in the SD transition energie s is also observed, suggesting the presence of terms with fourfold sym metry in the SD Hamiltonian.
