The Hamilton operator Ĥ of an atom with Z-electrons and Z-protons (in the nucleus) is given by (Schiff [51])
$$\hat{H} = - \frac{{{{\hbar }^{2}}}}{{2{{m}_{e}}}}\sum\limits_{{i = 1}}^{Z} {{{\Delta }_{i}} - \frac{{{{\hbar }^{2}}}}{{2{{m}_{N}}}}{{\Delta }_{N}} - \frac{{{{e}^{2}}}}{{4\pi {{ \in }_{0}}}}\sum\limits_{{i = 1}}^{Z} {\left( {\frac{Z}{{|{{r}_{i}} - {{r}_{N}}|}} - \sum\limits_{{j \ne i}}^{Z} {\frac{1}{{|{{r}_{i}} - {{r}_{j}}|}}} } \right)} }$$
where m e is the mass of the electron and m N the mass of the nucleus. The first term describes the kinetic contributions from the electrons and the second the kinetic contribution from the nucleus. The third term gives the interaction of the nucleus with the electrons (attractive force) and the fourth the interaction of the electrons (repulsive force)
