✦ Synopsis

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 are used. The correlation energy of the beryllium atom is calculated as an example.
