Model for the Growth of Fullerenes (C60, C70) from Carbon Vapour

A simple model for the growth of fullerenes (C60, C70) from carbon vapour is proposed. We assume that the growth process consists of adding hexagons and pentagons to the growing Cn cluster and involves kinetic and energetic factors. Thus, we are able to estimate curvature energy, the relative abundance of C60, C70, C84, etc., and the temperature dependence of fullerene formation.
