Using the liquid drop model, plot on the same graph, as a function of a, in units of mev/nucleon (a) the bulk volume binding energy per nucleon, (b) the negative of the surface binding energy per nucleon, (c ) the negative of the asymmetry contribution per nucleon, (d) the negative of the columbic contributing per nucleon, and (e) the total binding energy per nucleon ignoring the pairing terms. for a given a value, use z determined from eq. (3.18) for the most stable member of the isobar z(a)2
