Microscopic description of superdeformed bands in $^{190,192,194}$Hg
J. Libert1, J.F. Berger, J.P. Delaroche, M. Girod

Positive parity states at normal deformation and superdeformation (SD) are obtained for 190,192,194Hg by solving a microscopic collective Hamiltonian which is defined in terms of the five quadrupole degrees of freedom. Yrast and excited SD bands are predicted. Their properties are compared with experimental information. In particular, it is found that all the predicted dynamical moments of inertia J(2) are very similar, a feature consistent with that obtained from extrapolating the measured J(2)'s toward very low rotational frequencies. Excitations of two quasi-particle states are also considered.
