Toward global beyond-mean-field calculations of nuclear masses and low-energy spectra

Abstract

Self-consistent mean field (MF) and beyond-mean-field (BMF) calculations of masses, separation energies and $2_1^{+}$ excitation energies of even-even nuclei where experimental data is available are presented. The functionals used are based on the Gogny D1S and D1M parametrizations and the method includes beyond-mean-field corrections coming from both axial quadrupole shape mixing and symmetry restorations without assuming gaussian overlap approximations. A comparison between mean field, beyond-mean-field approaches and the experimental data is provided. Additionally, the convergence of the results and the possible reduction of the magic shell gaps by including BMF effects are also discussed.
