T?x Kato electron-electron cusp condition is used to derive a corresponding cusp condition for the spherical average of the intracule matrix. The numerical utility of this condition is illustrated by considering the Hart and Herzberg 20-parameter Hylleraas-type wavefunctions for the helium-like ions

Hartree-pock wavefunctions and good approximations to the exact wavefunctions are used to demonstrate the effect of electron correlation on the rrtditl density D(rr) and the contours of the density distribution p(rr) in the He isoehrctronic sequence. In genemi, correfation effects diminish as the ch
## Abstract The correlation potential is computed for two electron atomic ions with atomic numbers from 1 to 10 using the charge density reconstructed from a natural orbital expansion of a Kinoshita‐like atomic wave function. Over the wide range of densities involved, the correlation potentials are
