Abstract
The Hartree-Fock ground-state densities of neutral atoms can be utilized to approximate the electrostatic potential due to the electronic charge cloud at the nucleus. The correction due to electronic correlation is shown to involve the derivative of the correlation energy with respect to atomic number at constant number of electrons. Two theoretical expressions lead to quite similar partitioning of this derivative into the sum of two parts. Finally empirical estimates of the derivative are obtained and the small correction to the Hartree-Fock electrostatic potential at the nucleus is thereby found.
