For a nucleus \(\rm _Z^AX\) having mass number A and atomic number Z
A. The surface energy per nucleon (bs) = –a1 A2/3.
B. The Coulomb contribution to the binding energy \(b_c=-a_2 \frac{Z(Z-1)}{A^{4 / 3}}\)
C. The volume energy bv = a3A
D. Decrease in the binding energy is proportional to surface area.
E. While estimating the surface energy, it is assumed that each nucleon interacts with 12 nucleons. (a1, a2 and a3 are constants)
