Abstract : The three-body ionic recombination rate at low densities is calculated for a slightly ionized gas by considering that the relaxation of the energy of molecules occurs by a 'diffusion' process. The effective conductivity in the equivalent diffusion equation is the second moment of the energy transfer. The moments are derived in closed form using classical mechanics and enable the recombination rate constant to be obtained. The agreement of the results with experimental data is good and suggests that the diffusion approach is useful even where relatively large energy transfers are involved. (Author)
