M-Effect: monocromatization of the emission spectra of an electropositive-electronegative gas mixture — •Bianca Cudalbu, Alexandra Baltog, and Geavit Musa — National Institute for Lasers, Plasma and Radiation Physics, P.O.Box MG-36, 76900, Bucharest, Romania
M-effect
is the reduction of the neon emission spectra
practically to only one line of the wavelength 585.3
nm, when the filling gas is the mixture Ne + Ar +
H2 or Ne + Xe + H2. We explained the M-effect
as due to the ion-ion recombination according to the
reaction
Ne+ + H− → Ne*( 2p1) +
H, which feeds selectively the level 2p1 of the
neon transition 2p1 − 1s2 with the wavelength
585.3 nm. Knowing the real mechanism of the observed
process, we could extend our investigation to other
mixtures of electronegative gases with electropositive
gases. Not all electronegative-electropositive gas
mixtures present the M-effect, a fact not yet fully
explained. We may conclude that our obtained
experimental data clearly prove the general character
of the M-effect. It results that the M-effect
represents a new discovered physical process.
