The Monochromatization–effect of light (the so-called M-effect) consists in the reduction of an electronegative– electropositive gas mixtures discharge emission spectrum to only a few (or even one, in the particular case of H2 - Ne gas mixture) spectral lines, in A.C./D.C. discharges at moderate to high total pressures (tens to hundreds of mbar). The main reaction mechanism is the polar resonant three-body reaction, with the decisive contribution of the electronegative metastable atoms, which play the role of the third particle involved in reaction.The paper deals with the variance analysis of the polarization degree in H2-Kr gas mixture (νH2/νNe=27/38). The calculations were performed for different total pressures values (27,5 torr, 42 torr, 65 torr and 80 torr, respectively) of the gas mixture, taking into account the intensities of three spectral lines (λ=758,7nm, 760nm and 811nm), which appeared as dominant ones in frame of the M-effect. The calculation method used in the experiment was the “Two-way ANOVA method” which offers the possibility to follow the evolution of physical parameters of interest under different experimental conditions..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
