The binding energy of a light nucleus (Z, A) in MeV is given by the approximate formula
\(B(A, Z) \approx 16 A-20 A^{2 / 3}-\frac{3}{4} Z^2 A^{-1 / 3}+30 \frac{(N-Z)^2}{A}\)
where N = A - Z is the neutron number. The value of Z of the most stable isobar for a given A is
1
\(\frac{A}{2}\left(1-\frac{A^{2 / 3}}{160}\right)^{-1}\)
2
\(\frac{A}{2}\)
3
\(\frac{A}{2}\left(1-\frac{A^{2 / 3}}{120}\right)^{-1}\)
4
\(\frac{A}{2}\left(1+\frac{A^{4 / 3}}{64}\right)^{-1}\)
