Abstract

The Generator Coordinate Method with particle number projection using a set of Hartree-Fock plus BCS states is applied to the superdeformed even-even Hg and Pb isotopes. The q 30 and q 32 octupole vibrations are investigated in even-even Hg and Pb isotopes. These one-dimensional calculations predict that the collective octupole K π — 0 − excitations are the lowest mode in energy. The electric monopole E 0 decay out of superdeformed states is also compared to the electric quadrupole E2 transition rates.
