Popis:	Collisions of C+60, ions with clean and oxygen-covered Ni(100) surfaces have been studied under UHV conditions. We observed that in contrast to scattering from oriented graphite (HOPG) and diamond (111) Buckminster fullerene ions are not stable against collisions with a Ni(100) surface. AES and LEED measurements show a complete dissociation of the C+60 at this surface forming a c(2×2)C-p4g superstructure. Broad LEED extra spots, even for coverages below 0.33, are discussed to be the result of domain formation due to the peculiarities of such a kind of carbon deposition.
