THE MONOCHROMATISATION EFFECT OF RADIATION IN AC/DC MULTIPLE GAS MIXTURES DISCHARGES AND THE COMPARISON WITH THE EXCIMER RADIATION GENERATION MECHANISMS

摘要

The monochromatisation-effecl (M-effect) consists in the decrease of the emission spectra of an electronegative-electropositive gas mixtures discharge to only few intense spectral lines or even only one line, as in the case of Ne-H_2 gas mixture. In previous papers published it has been reported the study results related to the M-effect appearance in other different gas mixtures, both in AC and DC discharges. The present paper informs about the registered spectra obtained, the optimum values of the electronegative percentages corresponding to the maximum values of the M-parametcr, and the main mechanisms reactions responsible by the appearance of the M-effect by comparison with the generation mechanisms of excimer radiation.
