Through 12C/13C isotope scrambling measurements, the mechanistics of the initial stages of fullerene formation are unambiguously clarified. The distribution of 13C among the C60 molecules follows exactly Poisson statistics for every ratio of unmixed 12C and 13C in the feed of these arc plasma experiments. Furthermore no magic mass numbers are observed. This totally random scrambling shows not only that C60 is grown in the plasma but also that the starting point is atomic carbon vapour.
