It has been known since the work of March and White that the simplest nonrelativistic density functional theory, namely, the statistical method of Thomas, Fermi, and Dirac, sums subseries of the so-called 1rZ expansion to yield, for heavy neutral atoms, the ground-state energy E s ya Z 7r3 q a Z 2 y
The method of the evaluation of the upper and lower bounds of the second-order perturbation of the energy is described. The calculation of upper and lower bounds for the second-order perturbation of the energy in l/Z expansions for two-electron atoms are given.
