【 摘 要 】

It has been performed the nuclear ground state properties investigation of232Th and238U using Skyrme interaction. The local density, the kinetic energy density, and the spin-orbit density for proton and neutron have been calculated using Extended-Thomas-Fermi approach method. Then the calculation results have been compared with Skyrme-Hartree-Fock results (using HAFOMN and HFBRAD codes). Total energy calculations obtained from this research are -1792.973947 MeV (for232Th) deviated 0.29244% from experiment energy and -1761.519459 MeV (for238U) deviated 0.48369% from experiment energy. The distribution profiles of local density and local potential for232Th and238U are quite similar with Skyrme- Hartree-Fock results. It is indicated that Skyrme-Extended-Thomas-Fermi method can be used to study the nuclear ground state properties, especially even nuclei.
