Abstract
The structure properties of the even-even nuclei $\chem{^{226, 228, 230, 232, 234}Th}$, $\chem{^{230, 232, 234, 236, 238, 240}U}$ , $\chem{^{240, 242, 244, 246}Pu}$, and $\chem{^{242, 244, 246, 248}Cm}$ 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.
