Our studies, performed for (Kr+ H2) gas mixtures plasma in a RF discharge, at pressures
varying in the range of 27 to 80 torr, have put in evidence a clear reduction of the krypton
emission spectrum to practically only three spectral lines, considered as dominant in the
frame of M-effect namely 758, 7nm, 760nm and 811nm, respectively [1]. Due to the fact that
the modified spectrum is usually reduced to some dominant lines, the phenomenon was
called the “Monochromatization-effect”(M-effect). It is interesting to notice that a kind of …

Due to the fact that the modified spectrum is usually reduced to some dominant lines, the phenomenon was called the “Monochromatization-effect”(M-effect). It is interesting to notice that a kind of “cleaning” effect of the emission spectrum appears also in the case of the nitrogen plasma in which was added a very small quantity of hydrogen but yet there are important differences concerning the experimental conditions and the reaction mechanisms between the two types of plasma discharges [2, 3].
