    "abstract": "Variation of nuclear shell effects with nucleon numbers are evaluated using\nthe modified Bethe-Weizsacker mass formula (BWM) and the measured atomic\nmasses. The shell effects at magic neutron numbers N = 8, 20, 28, 50, 82 and\n126 and magic proton numbers Z = 8, 20, 28,50 and 82 are found to vary rapidly\napproaching the drip lines. The shell effect due to one magic number increases\nwhen it approaches another magic number. Thus, shell effects are not always\nnegligible near the drip lines.",
