Abstract:

The structure properties of the even-even nuclei 226, 228, 230, 232, 234Th, 230, 232, 234, 236, 238, 240U, 240, 242, 244, 246Pu, and 242, 244, 246, 248Cm have been investigated at normal and superdeformed shapes in microscopic mean-field calculations based on Gogny force. Collective levels are predicted from constrained Hartree-Fock-Bogoliubov and configuration mixing calculations. Two quasiparticle states are also predicted from blocking calculations for neutron and proton configurations. Predictions are shown and compared with experimental data at superdeformed shapes.
