Abstract
Fragmentation of C60 induced by He+ impact at 7Â keV and 18Â keV is studied as a function of the ejected electron number due to primary electronic excitation. The fragment mass distribution is found to depend only on the charge of the C60 but independent of the collision velocity. The shift of the ejected electron number to higher value at higher collision velocity allows to interpret the shift of the total TOF mass distribution with the collision velocity.
