Abstract

A new method for solving correlation pair equations for diatomics is presented and followed by numerical results for the H2 and LiH molecules. The essential feature of the new approach is a numerical representation of both basis two‐electron functions and Coulomb and exchange potentials in pair equations. It is shown that this significantly simplifies the pair function optimization procedure.
