Variation of nuclear shell effects with nucleon numbers are evaluated using the modified Bethe-Weizsäcker mass formula (BWM) and the measured atomic masses. The shell effects at magic neutron numbers N=8, 20, 28, 50, 82 and 126 and magic proton numbers Z=8, 20, 28,50 and 82 are found to vary rapidly approaching the drip lines. The shell effect increases when approaches another magic number. Thu...
