Effects of these two kinds of interaction on properties of atomic nuclei, especially the mass difference of mirror nuclei and the neutron-skin thickness of = and ≠ nuclei, are discussed. It is found that corrections to the Hartree-Fock-Slater approximation for the Coulomb interaction negligibly affect the neutron-skin thickness, while the charge-symmetry breaking term originating from the strong interaction might affect it non-negligibly. According to our calculations, the ISB terms other than the Coulomb interaction affect the estimation of the density dependence of the symmetry energy, , by about 0–12MeV using the correlation with the neutron-skin thickness.19 p.application/pdfeng(c) American Physical Society, 2023Estructura nuclearTeoria del funcional de densitatFísica nuclearNuclear structureDensity functionalsNuclear physicsinfo:eu-repo/semantics/article7451972024-10-18info:eu-repo/semantics/openAccess
