✦ Synopsis

The fullerenes C,, and C,, 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, units. Large internal energies are deposited into these molecular ions and the dissociation emciency is in excess of 60%.
