Abstract. The axial profiles of the electron number density and the densities of argon excited states as well as the densities of the atomic Ar+ and molecular Ar2+, Ar3+ ions are obtained using a self-consistent model, which includes an electrodynamic and a kinetic part. The electron and heavy particles balance equations, involved in the kinetic part of the model, are solved together with Maxwell's equations in the electrodynamic part. The argon ground state and seven excited states (4s, 4p, 3d, 5s, 5p, 4d, 6s) considered as blocks of levels are taken into account in the kinetic part of the model.
