| Résumé : | The latest developments made in deriving accurate mass predictions within the microscopic Skyrme Hartree-Fock-Bogolyubov (HFB) approach are described. These include an improved description of infinite nuclear and neutron matter, a reduced pairing strength and the inclusion of a phenomenological vibrational term. A special attention in the determination of the latest effective forces is paid not only to the nuclear ground state and nuclear matter properties, but also to nuclear level densities and fission barriers. The interplay between the Coulomb and the strong interaction is also analyzed, the associated Coulomb correlations being simulated by suppressing the Coulomb exchange energy. With our latest Skyrme force, BSk14, being refitted in this way, the Coulomb correlation effect is found to reduce the rms deviation with respect to experimental masses and to affect the nuclear mass predictions close to the neutron drip lines significantly. |
