Above the surface multifragmentation of surface scattered fullerenes
C-60(-) ions were scattered from a gold surface at impact energies of 80-900 eV. The C-n(-) fragments abundance distribution (odd and even) and the sharp fragmentation threshold observed, point at a prompt shattering event. The measured angle and energy distributions of the C-n(-) fragments (n=2-12) provide clear evidence for a multifragmentation process where the superheated fullerenes leave the surface "intact" and disintegrate away from the surface.
