Figure 2

Electron-pair density as function of the interelectronic distance, for the ground state of orthohelium. (a) Red line—no screening (no exchange), blue line—short-range screened Coulomb potentials. Exchange hole (b) for screened Coulomb potentials (black) and for Hartree-Fock exchange (green).
