The theory leads to single-particle equations of motion with a quasilocal mean-field operator, which contains a quasiparticle position-dependent effective mass and a spin-orbit potential. The energy density functional is constructed using the extended Thomas-Fermi approximation and the ground-state properties of doubly magic nuclei are considered within the framework of this approach. Calculations were performed using the finite-range Gogny D1S forces and the results are compared with the exact Hartree-Fock calculations14 p.application/pdfeng(c) The American Physical Society, 2003Teoria del funcional de densitatEstructura nuclearDensity functional theoryNuclear structureinfo:eu-repo/semantics/article506156info:eu-repo/semantics/openAccess
