Valence State of Copper in Nd2-Xcexcuo4
New photoemission data are presented for a series of Ce-doped or undoped, reduced or nonreduced, Nd cuprates. The data, taken with high signal-to-noise level in the constant-initial-state mode, demonstrate the presence of Cu+, in contrast with previous photoemission and electron-energy-loss studies.
