Description

Microscopic optical potential model, based on the calculations of the mass operator of the single-particle Green's function with NN-forces Skyrme was improved by using an extended version of NN-forces, including tensor and the nuclear density-dependent velocity terms and is used to simultaneously describe the structure of nuclei and NA-scattering. Parameters of the new option Skyrme forces are obtained from the analysis of neutron scattering cross sections and characteristics of the nuclear structure. It was proved an important role of velocity-dependent force terms depending on the density to improve the description of data. The properties of the even-even extreme neutron-rich nuclei were calculated beyond the known limits of neutron stability on the basis of the Hartree-Fock with Skyrme forces, assuming spherical symmetry or axial deformation. The influence of the tensor force on a neutron stability of nuclei was investigated for the nuclei forming peninsula of stability outside the limits of neutron stability, It was proved that the peninsula of stability with respect to emission of a neutron for N = 32, 58, 82, 126, 184 are not sensitive to the Skyrme forces, including tensor component. Spin-polarised states in neutron matter in a strong magnetic field were studied in the model with Skyrme effective forces (for SLy7 parameterization ). Self-consistency equation for finding the parameters of the spin polarization and the chemical potential of neutrons were obtained and analyzed at zero temperature.
