Abstract: | Present-day self-consistent approaches in nuclear theory were analyzed from the point of view of describing distributions
of nuclear densities. The generalized method of the energy density functional due to Fayans and his coauthors (this is the
most successful version of the self-consistent theory of finite Fermi systems) was the first among the approaches under comparison.
The second was the most successful version of the Skyrme-Hartree-Fock method with the HFB-17 functional due to Goriely and
his coauthors. Charge radii of spherical nuclei were analyzed in detail. Several isotopic chains of deformed nuclei were also
considered. Charge-density distributions ρ
ch(r) were calculated for several spherical nuclei. They were compared with model-independent data extracted from an analysis
of elastic electron scattering on nuclei. |
