    "abstract": "A mass formula (BWM) without shell effect is employed to study the variation\nof the shell effect in Pb isotopes through comparison with the experimental\ndata. Unlike other macroscopic formulae, the BWM reproduces the general trend\nof the binding energy versus neutron number curves of all the nuclei from Li to\nBi. The shell effect in Pb-isotopes reduces to ~56 keV at N=106 but, increases\ngradually for N\u003c106, indicating increasing shell effect in Pb near the proton\ndrip line.",
