✦ Synopsis

Abstract

An antisymmetric pair function can be built upon two kinds of monoelectronic functions, the former ones being correlated local functions and the second ones nonlocal functions taking external effects into account. This function, brought into the generalised product function procedure by means of the density matrix formulation, makes possible the study of correlation within N‐electronic systems. The results of a first application of this method to the fundamental and to ^1^P and ^3^P excited states of two‐electron systems are given.

## Abstract The self‐correlated field method is based on the insertion in the group product wave function of pair functions built upon a set of correlated “local” functions and of “nonlocal” functions. This work is an application to three‐electron systems. The effects of the outer electron on the i
