## Abstract Pair energies contributing to the correlation energies of the outerโ€shell electrons (__n__ = 3) as well as for the 1__s__^2^ and 2__s__^2^ pairs are computed for the Zn^2+^ closedโ€shell ion by means of the variationalโ€perturbation method starting with the sum of oneโ€electron Hartreeโ€“Foc

The electron density entering the kinetic potential of the local-density-approximation method can be corrected by using the density derived from the exchange potential. The resulting correction to the kinetic energy density is similar in form to the gradient terms obtained by Alonso and Girifalco on
