Abstract

Several doubly excited autoionizing states of He have been calculated within the density functional framework by employing the Harbola-Sahni exchange potential. Correlation effects have been incorporated in the total effective potential through a Wigner-type correlation potential. Although continuum functions are not explicitly incorporated into these calculations, resonance energies of these states are in satisfactory agreement with other theoretical results.
