Abstract: | Possible reactions by which small carbon molecules C2 and C3 can join a cluster at an intermediate assembly stage from a two-ring cluster to a fullerene are considered. For analysis
of the separate stages of this type of reaction, methods of quantum chemistry are used. The generalized reaction probabilities
obtained are then included into the general scheme of assembly kinetics alongside monomolecular reactions. It has been shown
that at a small cluster concentration of about 1014 cm−3 the assembly time drops severalfold. Also given are generalized results of the effect on the assembly time of the multiplicity
of paths of fullerene assembly from two-ring clusters. |
