Abstract : A perturbation method for the one-electron density matrix in the matrix formulation of the Hartree-Fock approximation, is developed. Application of the method requires no knowledge of the eigenvalues and eigenvectors of the unoccupied orbitals. It is applicable to closed shell systems in the restricted Hartree-Fock approximation, and to any system in the unrestricted Hartree-F OCK APPROXIMATION. (Author)
