Abstract
The electron energy distribution function (eedf) in expanding nitrogen arcs has been obtained by solving a Boltzmann equation including elas tic, inelastic, and superelastic terms. Different realistic hypotheses on the concentrations of vibrationally and electronically excited sta tes as well as on the ionization degree have been assumed. The results show that eedf and related coefficients are strongly dependent on the concentrations of excited states that superimpose structures to the b ulk of eedf.
