Comparative studies of MO resonances and MG responses with and without resonant laser irradiation were carried out to establish the interconnection of the effects and the influence of the self-alignment destruction on the MO signal in positive column discharge. These studies aim to clarify the possible formation mechanisms of the neon 1s_i (2p⁵3s) states coherences and to examine the possibility to use the galvanic resonances for estimation of the relaxation constants of the neon ls₅ state.
