Notes:
A direct graphical approach is presented for the evaluation of matrix elements of a spin-free Hamiltonian between Slater determinants of nonorthogonal orbitals. The matrix element contributions are obtained by repeated use of N - 2 electron minors of the overlap matrix that are generated by independent looping of reduced N - 2 electron graphs for the α- and β-strings of the determinants. Because of the successive generation of the matrix contributions, the method is well suited for direct diagonalization schemes.
