The nuclear binding energy may be approximated by the empirical expression b(a, z) a1a-az4/-0322 a1/3-a(a-22)a (a) explain the various terms in this expression. (b) considering a set of isobaric nuclei, derive a relationship between a and z for naturally occurring nuclei. (c) use a fermi gas model to estimate the magnitude of a,. you may assume a nuclear radius is r roa/s. 22 and that the
