| Abstract: | Triple differential cross-sections (TDCS) for ( e ,2 e ) 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 ,2 e ) experiment in specular geometry using a thin film of physisorbed C60. Received 14 April 2000 and Received in final form 27 July 2000 |
