New magic numbers and new islands of stability in drip-line regions in mass model Original Research Article

The systematics of the local energies and the two-neutron separation energies obtained in the mass predictions of infinite nuclear matter model of atomic nuclei and relativistic mean field study with NL3 interaction show strong evidence of new neutron magic numbers 100, 150, 164, new proton magic number 78 and new islands of stability around N = 100, Z ⋍ 62; N = 150, Z = 78; and N = 164, Z ⋍ 90 in the drip-line regions of nuclear chart. The usual magic numbers seen in the valley of stability are found to be no more valid in such regions.
