Beginning with the Weizsäcker semi-empirical mass formula, show
that the minimum in a mass parabola occurs at a value of atomic
number, Zmin, given by
Note: The Weizsäcker semi-empirical mass formula for the binding
energy, B, of a nucleus is where A is the atomic mass number of the
nucleus and Z is the atomic number of the nucleus. Hint: Although
atomic number, Z, only takes integer values, assume it is a
continuous variable for the purpose of this exercise....
