Addendum to: “A variational density-functional calculation of the total atomic binding energy with recently proposed kinetic–energy and exchange–energy functionals”^†

Using hydrogen-like wave functions, a two-parameter and a four-parameter variational density-functional calculation of the total atomic binding energy of Ne atom is carried out. The total-energy values, together with values obtained for the electron (number) density at the nucleus, are compared with a previous three-parameter variational density-functional calculation and with single-zeta Hartree-Fock values.
