Interaction of varying coverages of Ni metal with solid films of C₆₀ and C₇₀ has been investigated by UV and X-ray photoemission spectroscopy. The shifts in the valence bands of C₆₀ (as well as of C₇₀) with increasing Ni coverage accompanied by a shift of the C 1s level of the fullerene to lower binding energies suggest charge-transfer from the metal to the fullerene as in transition metal complexes of π-systems.
