Influence of the H 2 and SF 6 addition to Ne + 1%Xe on the narrow barrier discharge spectral radiation

Self Cite

The experimental results concerning the influence of the H 2 and Ar addition to the Ne+1% Xe Penning mixture on the neon optical emission are obtained for two types of discharges: a narrow gap dielectric barrier discharge and the negative glow of a d.c. luminescent discharge. The H 2 and Ar contribution to the depletion of the lower level 1s 2 through the Penning collisions and also the hydrogen participation to the feeding of the upper level 2p 1 of the optical transition 2p 1 -1s 2 of the neon have been demonstrated. As a possible explanation for feeding of the upper level 2p 1 we are favouring the reactive and/or dissociative recombination processes.

Polar recombination as the main process explaining the M‐effect

A full explanation of the M-effect, namely the reduction of the neon emission spectra practically to only one line of wavelength ½ ¿ nm, when the filling gas is a mixture Ne + Ar + H¾ or Ne + Xe + H¾ is presented.The M-effect is explained by ion-ion recombination according to the reaction Ne · · H Ne £´¾ Ô½µ·H, which feeds selectively the level ¾Ô½ of neon. All observed behavior of the M-effect is explained by polar recombination. Extension of the M-effect to other gas mixtures containing at least one electronegative component is also underlined.
