摘要：
Triple differential cross-sections (TDCS) for (e,2e) processes on C60 have been calculated in the plane wave Born and distorted wave Born approximations using a jellium shell model to describe the target valence states. The peculiarities of these TDCS are demonstrated by comparison with results for atomic hydrogen. Ionisation into a resonant state leads to dramatic modifications of the TDCS. This effect could also be observed in a surface (e,2e) experiment in specular geometry using a thin film of physisorbed C60.
