## Abstract It is pointed out that if a many‐electron antisymmetric wave function is expanded as a sum of spin‐product functions, each multiplied by a function of coordinates, the resulting functions of coordinates have many of the same useful features found with the symmetric and antisymmetric fun

## Abstract A method of calculation of the correlation energy is proposed, which includes the superposition of configurations and the two particle approach. This method is based on the density matrix formalism. The approximate, but __N__‐representable expressions for the reduced density matrices ar
