It kinetic model of the fullerene growth process in a contact are gene
rator is developed. On the basis of the kinetic model, the yield of th
e magic fullerenes C-60 and C-70 is calculated. The fullerene yield is
determined by the temperature gradient in the fullerene formation zon
e, the carbon vapor concentration and the helium jet velocity in the i
nterelectrode space. We found that the upper boundary value of the mag
ic fullerene yield was about 20%.
