ABSTRACT

At the fullerene synthesis in discharge plasma carbon clusters may be charged. The size and the sign of a charge depend both on itself cluster characteristics and plasma parameters — electronic concentration, temperature, etc. The influence of cluster charges on their coagulation and fullerene formation has been shown experimentally and theoretically. In a number of works the equilibrium approach has been used for the determination of carbon cluster charges. In the given work more consecutive physical model describing the kinetics of cluster charging is considered.
