Berrondo and Goscinski have proposed a functional dependence of the exchange energy kernel on the electron density. Their approximate exchange energy kernel is compared with the exact exchange energy kernel obtained from Hartree-Fock wavefunctions for neon, argon, and zinc. The Berrondo-Goscinski fu
