Abstract
Valence-level and Cu core-level photoemission spectra for in both metallic () and nonmetallic () phases are presented together for the first time. The core spectra show evidence for holes in the hybrid 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.
