Description
Summary:The direct variational method have been applied to the calculation of the symmetry energy for medium and heavy nuclei. The functional of energy of the Thomas - Fermi approximation with the effective Skyrme forces have been used. The behavior of the bulk and the surface symmetry energy as the function of the bulk nucleon density ρ q,0 and the neutron excess have been studied for the various sets of Skyrme forces. We have calculated the average number of neutrons in the surface region, Nd , for the nuclei at the line of β-stability and the dependence of Nd on the nucleon density ρ q,0 and on the remoteness from the line of β-stability.
