Résumé : New nuclear level densities based on the microscopic statistical model are proposed for practical applications. The statistical calculations are performed using the deformed Hartree-Fock-BCS predictions of the ground-state structure properties. The microscopic model includes a consistent treatment of the shell effects, pairing correlations, deformation effects and collective excitations. It predicts the experimental neutron resonance spacings with a degree of accuracy comparable to that of the phenomenological back-shifted Fermi-gas-type formulae. The microscopic level densities are renormalized to the existing experimental data, namely the s-wave neutron resonance spacings and the cumulative number of low-lying levels. Level densities for more than 8000 nuclei are made available in a table format for practical applications. © 2001 Elsevier Science B.V.
