## Abstract Most commonly the nonorthogonality of geminals is weakly expressed so that the exchange and overlap integrals ζ^(η)^, φ^(η)^ are negligible for large exchange parameters η. The conditions which allow the terms with large η to be discarded are considered. The integrals ζ^(η)^, φ^(η)^ are

## Abstract A scheme for obtaining approximate solutions of the electronic Schrödinger equation is formulated within the context of the method of moments. The flexibility of the method of moments is utilized in the construction of a model based on an antisymmetric product of geminals (APG). This AP
