Description
We have added a weakly repulsive external potential to the self-consistent mean field in Hartree-Fock-bogoliubov calculations in order to see the responses of the low angular momentum orbitals to a shallowing potential. It is seen that the bound state nature of the d5/2 and s1/2 quasi-particle states in neutron-rich Ni isotopes are very sensitive to the form of the pairing interaction employed and to the depth of the mean field. When the system gets less bound, the odd-even staggering in the charge radii as well as the effect of the tensor force on the shell gap are expected to be reduced.
