A model reaction system is considered consisting of a heat bath of argon atoms (c) and small concentrations of SF 6 ‐molecules ( m ) and electrons ( e ) (number densities: n e ≪ n m ≪ n c ). Within the model the time behaviour of the electron velocity distribution function is studied under the influence of elastic electron‐argon collisions and electron SF 6 attachment collisions. On the basis of the distribution function time‐dependent macroscopic quantities (kinetic electron temperature. nonequilibrium rate constant of the attachment reaction) are calculated.
