Conclusions 1. It is shown that the soot recovered on the deposition surface of a diffusion jet of methane is enriched in the heavy isotope of carbon the more, the greater the height of this surface is located. This enrichment is explained by the high rate of diffusion of methane molecules containing the light carbon isotope, which leads to enrichment of the methane in the heavy isotope. 2. The soot, formed from methane in the flame of a plane burner, is enriched in the light carbon isotope, which is explained by the isotopic kinetic effect of the growth process of soot particles. 3. The soot, deposited on the surface at the height of its maximum yield in a diffusion jet of methane, is enriched in the heavy carbon isotope the more so the closer it is located to the axis of the jet. 4. The zone of soot formation of a diffusion laminar jet expands from below upwards, due to the involvement in the soot formation process of new layers of gas. In the lower part of the jet, this expansion takes place because of the outside layers of gas, and in the zone of main soot formation because of the inner layers of gas.
