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.
