Kinetics of Collision Processes in Dilute Noble Gases

Abstract

Kinetics of collision processes is analyzed for dilute noble gases within a linear approximation. Dilute gas is treated as a chemically reacting mixture of dimers and monomers. Two elementary reaction models are analyzed employing theoretical rate constants calculated recently from quasiclassical trajectories. Stability of stationary states and relaxation of small concentration perturbations are treated in terms of linearized kinetic equations. The results obtained are generalized for heavier noble gases (neon to xenon). Helium is, because of quantum nature, analyzed separately.
