Na. Gorbunov et al., Effect of negative electron mobility in a mixture of argon, molecular nitrogen and optically excited lithium vapours, PLASMA SOUR, 8(4), 1999, pp. 544-552
Parametric computations of the electron energy distribution function and of
the electron mobility in a photoplasma of a lithium vapour mixture: with a
rgon and molecular nitrogen are presented. The possibility of the occurrenc
e of a steady-state negative electron mobility when using a certain ratio o
f mix components under optical resonant excitation of the Li(2S-2P) transit
ion is considered. The critical plasma parameters (the lithium excited atom
ic density, the temperature of the vibrational distribution of nitrogen mol
ecules, the plasma ionization degree, the external electric field strength)
determining this effect are revealed.
