Mechanisms of radiation stimulated modification of fullerenes

Summary form only given. This paper deals with theoretical investigation of radiation influence on fullerenes. Our approach is based on the cross-word system. Irradiation affects by means of four basic factors: elastic displacement of atoms, ionization, shock waves, heat emission. All radiation induced macroeffects can be devided into following successive elementary processes: defect production, diffusion, quasichemical reactions. Therefore our research is construction of basic models for each fundamental factor response to any type of elementary process, taking into account peculiarities of geometric and electronic fullerenes structure. For example, on this base we constructed a model for elastic and Auger defects production, electron stimulated diffusion of single atom C and dumbbell C/sub 2/ quasichemical reaction of displaced atom C recombination with the vacancy V.
