The occupied and unoccupied valence-band density of states of YBa/sub 2/Cu/sub 3/O/sub 7-//sub delta/ is determined considering a coherent potential which includes the Coulomb intrasite d-d correlation. The p states tend to be all occupied and, as a consequence, the most localized d states with the XZ symmetry tend to be unoccupied giving rise to an upper Hubbard band. This picture is in good agreement with the direct and inverse photoemission spectroscopies.
