N2 - We report bulk-sensitive hard x-ray (hν=5.95 keV) core-level photoemission spectroscopy (PES) of single crystal V1.98 Cr0.02 O3 and the high- Tc cuprate Bi2 Sr2 Ca Cu2 O8+δ (Bi2212). V1.98 Cr0.02 O3 exhibits low binding energy "satellites" to the V 2p "main lines" in the metallic phase, which are suppressed in the antiferromagnetic insulator phase. In contrast, the Cu 2p spectra of Bi2212 do not show temperature-dependent features, but a comparison with soft x-ray PES indicates a large increase in the 2 p5 3 d9 satellites or 3 d9 weight in the bulk. Cluster model calculations, including a full multiplet structure and a screening channel derived from the coherent band at the Fermi energy, give very satisfactory agreement with the experiments.
