Reply to ``Comment on `Significance of the highest occupied Kohn-Sham eigenvalue' ''
Abstract
I give an additional argument that the proof of Perdew et al., stating that the highest occupied Kohn-Sham eigenvalue equals the ionization energy, is flawed. I also argue that the new proof given by Perdew and Levy in the preceding paper is wrong. The significance of the result for the two-electron ``Hooke's atom'' is then discussed.
