Abstract
In an earlier study, the exchange energy density epsilon(x)(r) has been calculated analytically for Ne-like atomic ions in the nonrelativistic limit of large atomic number Z. Here, though now by numerical methods based on the optimized exchange potential approximation, corresponding results are obtained for V-x(r) for such ten-electron ions at large Z. The approach to the bare Coulomb limiting form of the 1/Z expansion is considered in some detail, as are corrections to the Slater potential V-x(Sl)(r), given in terms of the exchange energy density and ground-state density rho(r) by 2 epsilon(x)(r)/rho(r).
