Description
Valence-level and Cu 2p core-level photoemission spectra for YBa2Cu3O/sub 7-//sub x/ in both metallic (x<0.5) and nonmetallic (x>0.5) phases are presented together for the first time. The core spectra show evidence for holes in the hybrid Cu 3dO2$p valence levels in the metallic state, but nonetheless the density of states at the Fermi energy seen in valence-level photoemission is at most 0.05 states/eV cell
