Kinetic theory is presented which proposes an explanation of a carrier gas effect on nucleation in DCC. The main idea of this theory is that for DCC transport of condensing molecules to the cluster surface is determined by their diffusion through a carrier gas that results in new kinetic equations or, in other words, in usual kinetic equations where rate constants of the cluster formation depends upon carrier gas pressure. Analytical dependencies of critical supersaturation S[sub *] and derivative ∂S[sub *]/∂T on a carrier gas pressure P[sub 0], temperature T and the nature of the carrier gas are derived that reproduce experimental data of Heist and co-authors.
