Remarks

・Binding Energy=Volume term Energy+Surface term Energy+Coulomb term Energy+Asymmetry term Energy+Pairing term Energy.
・Volume term Energy=av*A.
・Surface term Energy=-as*A^(2/3).
・Coulomb term Energy=-ac*Z^2/A^(1/3).
・Asymmetry term Energy=-aa*(N-Z)^2/A.
・Pairing term Energy=ap*A^(-3/4)(Case:Both Z and N are even).
・Pairing term Energy=-ap*A^(-3/4)(Case:Both Z and N are odd).
・Pairing term Energy=0(Other).
