چکیده انگلیسی
Using Skyrmeʼs density dependent interaction the evolution of nuclear shells has been studied by Hartree-Fock theory. Optimization of the effect of tensor interaction has been done by reproducing the observed splitting of shell model states of 40,48Ca, 56Ni and 208Pb. Splitting of spin-orbit partners in Ca isotopes, 56Ni, 90Zr, N=82 isotones, Sn isotopes have been studied and evolution of gaps in Z,N=8,20,28 have been reanalyzed with the inclusion of tensor interaction. Magic gaps for shell closed nuclei have been evaluated. For doubly shell closed nuclei it has been observed that tensor interaction is sensitive to spin saturation of nuclear shells. Spin-orbit splitting of single particle states evaluated through tensor interaction act as pointers of shell structures.
