“…Realistic shell-model calculations that employ the deformed Nilsson states as the model basis are used to validate the modification discussed above, through comparing the shell-model results directly with experimental data. The PSM [43] is a useful method of this kind, which has been successfully applied for different mass regions in the nuclear chart [6,7,[44][45][46]. In the PSM calculation, the deformed quasiparticle basis is first generated by the Nilsson model.…”

There has been compelling evidence indicating that deformed single-particle (SP) states in neutron-rich regions are different from those in the stable region. It was pointed out that for the light rare-earth (60Nd, 62Sm, and 64Gd), neutron-rich (N = 98 − 102) nuclei, the Woods–Saxon potential, the Nilsson modified oscillator potential with ‘universal’ parameters, and the folded Yukawa potential all failed to describe the correct ordering of neutron SP states. The location and size of deformed shell gaps in this mass region are under current debate. We propose a modification for the ‘standard’ Nilsson parameters of Bengtsson and Ragnarsson introduced in 1985. The proposed N-dependent spin–orbit interaction causes directly changes in deformed shell gaps with neutron number and deformation. By applying the modified Nilsson parameters to generate deformed bases for the projected shell model, we demonstrate that the calculation can explain consistently the current experimental data, including the ground state configuration in odd-neutron nuclei, upbending of the yrast moment of inertia at higher spins and the energies of 2-quasineutron 6− and 4− isomers in even–even nuclei.
