Abstract:
We analyze the equation for the highest occupied state in a system of noninteracting electrons in the density functional method. More rigorously than in the currently known publications, we show that the eigenvalues of this equation determine the ionization energy. In this case, the expression for the exchange-correlation potential is essentially refined.
