The discovery of cage-like carbon molecules (C{sub 60}, C{sub 70}{hor_ellipsis}) by H. Kroto et al. in 1985 sparked the imagination worldwide and resulted in an explosion of research activities. The greatest open question is how such compact structures form so efficiently, It is known from an isotope-scrambling experiments that the fullerenes result from the condensation of carbon atoms in the hot carbon vapor. Several pathways have been suggested but while there is no direct experimental evidence against any of the proposed mechanism, there is not any strong evidence in their favor. Thus it seems reasonable to study the yield of fullerene formation with the simultaneous diagnostics of carbon plasma. Such an approach could give new insights into fullerene formation mechanistics.
