The liquid drop model may be used to determine the nuclear binding energy for an isotope. This model uses the semiempirical binding energy formula, which takes into consideration four major effects (one term per effect) that contribute to the nuclear binding energy. The semiempirical binding energy formula may be expressed as: Z(Z - 1) C3 A1/3 (N – z)2 E, = C;A – C,A?/3 A The first term is the volume term, the second is the surface term, the third is the Coulomb term, and the fourth is the symmetry term. For nuclei having A 2 15, the constants have the following values: = 15.7 MeV, C, = 17.8 MeV, C3 = 0.71 MeV, and C. = 23.6 MeV 56 (a) Use the semiempirical binding energy formula to determine the nuclear binding energy (in MeV) for the isotope Fe. 26 MeV (b) Determine the percentage contribution to the binding energy by each of the four terms. (You should expect positive and negative values, but the sum should be 100%. Due to the nature of this problem, do not use rounded intermediate…

(a) In the liquid-drop model of nuclear structure, why does the surface-effect term -C2A2/3 have a negative sign? (b) What If? The binding energy of the nucleus increases as the volume-to-surface area ratio increases. Calculate this ratio for both spherical and cubical shapes and explain which is more plausible for nuclei.
