Based on UV and X-ray photoelectron spectroscopy, it is shown that nickel metal clusters deposited on solid C60and C70films cause marked changes in the valence band spectra. In addition, the C 1s core-level of the fullerenes shift to lower binding energies while the Ni 2p3/2core level shifts towards higher binding energies, especially at small metal coverages. These observations signify the occurrence of charge-transfer from the nickel metal to the fullerene. We also show that CO adsorbs weakly on C60and C70surfaces.
