Abstract :
The statistical correlation between a pair of electrons in Hartree–Fock orbitals is measured by mutual information and studied in position and in momentum space. We show that there are same- and opposite-spin orbital pairs where the correlation is larger in momentum space. Among these are opposite-spin valence shell pairs where the correlation arises from the indistinguishability of electron spins.
