Corrections to the Thomas-Fermi model of the atom

Abstract

A WKB approximation to the Hartree equations for an atom, taking the 1 r singularity of the potential into account, is developed. This in turn allows us to obtain in a systematic way the Z -1 3 and Z -2 3 corrections to the Thomas-Fermi model of the atom. Such a procedure is used to obtain a finite change density at the nucleus, which agrees well with Hartree-Fock values. © 1982.
