A simple collisional-radiative model is applied to plasma jet expansions in the case of Ar-O₂ mixtures in order to calculate the population densities of the electronic states of the neutral atomic species Ar and O. Are included in the calculation: the direct excitation and de-excitation of Ar and O by electron collisions, excitation transfers between heavy species (Ar-Ar, Ar-O, Аr-О₂, O-O₂ and O-O collisions), and spontaneous radiative decay of Ar and O atoms. The results are compared with the experimental data obtained by three different experiments.
