Abstract
Using Skyrme’s density dependent interaction the evolution of nuclear shells has been studied in Hartree-Fock formalism. Optimization of the strength of tensor interaction has been done in reproducing the observed splitting of shell model states of 40, 48 Ca, 56 Ni and 208 Pb. Spin-orbit splitting in Ca-isotopes, 56 Ni, 90 Zr, N = 82 isotones, Sn-isotopes and evolution of gaps in Z , N =8, 20 have been reanalyzed with the inclusion of tensor interaction. For doubly shell closed nuclei it has been observed that tensor interaction is sensitive to spin saturation of nuclear shells.
