    • Abstract

       

      Melting of $N = 20$ shell and development of $N = 16$ and 32 shells for neutronrich nuclei have been studied extensively by including tensor interaction in Skyrme–Hartree–Fock theory optimized to reproduce the splitting $\Delta 1 f$ shells of 40,48Ca and 56Ni nuclei. Evolution of gap generated by the energy difference of single-particle levels $v2s_{1/2}$ and $v1d_{3/2}$ has been found to be responsible for shell closure at $N = 16$. The splitting pattern of spin–orbit partners $2p$ shell model state in Ca, Ti, Cr, Fe and Ni isotopes indicates the formation of a new shell at $N = 32$ region.
