    "abstract": "We present the evolution of the shell structure of nuclei in Hartree-Fock\ncalculations using Skyrme\u0027s density-dependent effective nucleon-nucleon\ninteraction. The role of the tensor part of the Skyrme interaction to the\nHartree-Fock spin-orbit splitting in spherical spin unsaturated nuclei is\nreanalyzed. The contribution of a finite range tensor force to the spin-orbit\nsplitting in closed shell nuclei is calculated. It is found that the exact\nmatrix elements of a Gaussian and of a one-pion exchange tensor potential could\nbe written as a product Skyrme\u0027s short range expression times a suppression\nfactor which is almost constant for closed shell nuclei with mass number $A\\geq\n48$. The suppression factor is $\\sim 0.15$ for the one-pion exchange potential.",
