Abstract：
We systematically analyze the formula of the mass difference between the odd and even nuclei and its connection to the energy gap parameter. By calculating the mass difference of ten isotope chains near Sn and Pb, we find that all the shell structure, the pairing interaction and the nuclear deformation affect the value of Δ(3)n considerably. A modified formula of mass difference is proposed.
