摘　　要：The influence of the tensor interaction of nucleons on the characteristics of neutron-rich silicon and nickel isotopes was studied in this work.Tensor forces are considered within the framework of the Hartree-Fock approach with the Skyrme interaction.The addition of a tensor component of interaction is shown to improve the description of the splittings between different single-particle states and decrease nucleon-nucleon pairing correlations in silicon and nickel nuclei.Special attention was directed toward the role of isovector tensor forces relevant to the interaction of like nucleons.
