In - collisions, quintuply charged fullerene is produced via multiple electron capture by slow highly charged ions from neutral fullerenes. Quasi-symmetric charge division (3, 2) is observed in asymmetric mass division fission processes, i.e. (). In such fission channels, the charge density of the doubly charged light fragment is much higher than that of the triply charged heavy one. The measured population distribution as a function of the mass of the doubly charged fragment m is interpreted tentatively by fission barrier analyses.
