Abstract

The correlation potential is computed for two electron atomic ions with atomic numbers from 1 to 10 using the charge density reconstructed from a natural orbital expansion of a Kinoshita‐like atomic wave function. Over the wide range of densities involved, the correlation potentials are not even approximately a local function of the density.

## Abstract The difference in the electron correlation between H^‐^ and other two‐electron atoms is clarified by the introduction of the __r__~12~ term in the wave function. By using the expansion of __r__~12~, a certain modification of the usual electron correlation factor 1 + __Cr__~12~ is introd

The correlation effect for two-electron atomic systems has been taken into account by modifying the potential of the electron interactions appearing in the Hartree-Fock equation. The correlation energies obtained for H-, He, Li+ and Be 2t-differ by less than 20% from the exact values.
