Collisionally induced multifragmentation of ${\mathrm{C}}_{60}$

The inclusive yield distribution of ${\mathrm{C}}_n^{+}$ fragments from 45 keV ${\mathrm{C}}_{60}^{-}$ collisions with Ar gas, exhibits comparable yields for fragments with n in the 10–25 range and for fullerene fragments with n in the 40–58 range. Single-collision two-fragment coincidence measurements show a high probablity for formation of two fragments with similar size in the $n=15\mathrm{}–25$ range. Three ${\mathrm{C}}_n^{+}$ fragments each with $n>\mathrm{}2,$ have been observed in triple coincidence measurements. An enhancement of the yield of the lightest fragments with an odd number of carbons is observed.
