| Résumé : | Motivated by recent extensions of the Gogny force standard expression [1], we present here a new Hartree-Fock-Bogoliubov nuclear mass model based on an effective interaction including three ranges in the central term, employing a fitting procedure that includes a self-consistent account of quadrupole correlation energies within the 5-dimensional collective Hamiltonian approach. The newly adjusted parameterization, namely D3G3M, is the first of the Gogny type allowing to obtain all together a root mean square deviation as low as 870 keV over the 2457 nuclear masses accessible in the 2020 atomic mass evaluation, a stiff equation of state in neutron matter compatible with observed evidence for M>2M⊙ heavy pulsars, and a correct neutron to proton effective masses hierarchy in asymmetric nuclear matter, making D3G3M both suited for nuclear structure calculations and astrophysical applications. |
