MULTIPLE SUPERDEFORMED BANDS IN HG-194 AND THEIR DYNAMIC MOMENTS OF INERTIA

Three superdeformed bands have been observed in 194Hg. The dynamical moment of inertia J(2) of all three bands is observed to increase by 30-40% over the frequency range h{stroke}ω = 0.1-0.4 MeV. This phenomena can be understood in terms of the gradual alignment of pairs of high-j intruder orbitals within the framework of the cranked Woods-Saxon and Nilsson models including pairing. The calculations together with the observed J(2) behaviour of the three bands indicate that pairing correlations in the superdeformed minimum are rather weak. © 1990.
