The fullerenes C 60 and C 70 can be ionized by desorption from a liquid matrix upon bombardment by Cs + ions of 7 keV kinetic energy. The resulting radical cations, when activated in the ion trap by collisions with Xe target, in the presence of helium, undergo extensive dissociation by loss of multiple C 2 units. Large internal energies are deposited into these molecular ions and the dissociation efficiency is in excess of 60%.
