Abstract

We consider the x-ray photoemission, inverse photoemission, and CuL3VV Auger spectra of the high-Tc superconductors. We conclude that the on-site correlation energies of the Cu 3d electrons are large and that the energy of the Cu d8 configurations is clearly too high for d8 configurations to play a significant role in the ground state.
