• Skyrme-Hartree-Fock approach to the change of level occupancy of low mass halo nuclei

With a new parameterization of potential parameters which reproduces the ground state properties of shell closed nuclei fairly accurately, the role of occupancy of 2s1/2 level in determining the halo structures of 17O, 16N, 15C, 14B, 13Be have been investigated. The results show interesting cross over of level occupancies which may explain the increase in interaction radii.

• Emergence of new magic numbers, $N = 16$ and 32 by tensor interaction in Skyrme–Hartree–Fock theory

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.
