The interacting electron Hamiltonian H = H_{D}+∑_{K,ζ}H_{K,ζ} is considered in the Hilbert space spanned by Slater determinants of Bloch wave functions. H_{D} consists of the diagonal part of H in this basis. K and ζ=0, ±1 stand for the total momentum and projected spin of electron pairs and H_{K,ζ} is the off-diagonal part of H describing the most general two-electron scattering process conserving K and ζ. It is shown that the eigenspectrum of H includes all eigenvalues of H_{D}+H_{K,ζ} for every K and ζ value. The associated eigenvectors of H are shown to have off-diagonal long-range order.
