The Formula
In the following formulae, let A be the total number of nucleons, Z the number of protons, and N the number of neutrons.
The mass of an atomic nucleus is given by
where and are the rest mass of a proton and a neutron, respectively, and is the binding energy of the nucleus. The semi-empirical mass formula states that the binding energy will take the following form:
Each of the terms in this formula has a theoretical basis, as will be explained below.
