A series of publications devoted to the study of collisional deactivation of Xe atoms in the 6s and 6s' states in high-pressure Ar - He and He - Xe mixtures with a low content of Xe is summarised. The processes of quenching of the *P{sub 1}, *P{sub 0}, *P{sub 1}, and *P{sub 2} levels are studied in two-particle Xe*+Ar(He) {yields} products+Ar(He), three-particle Xe*+ 2Ar(2He) {yields} ArXe*(HeXe*+Ar(He), and three-particle Xe*+Xe+Ar(He) {yields} Xe*{sub 2}+Ar(He) collisions. The gases were excited by a fast-electron beam. The measurements were performed by the method of absorption probing by analysing the time dependence of the concentration of the excited states in the afterglow of the electron beam. The rate constants of 24 plasma-chemical reactions were measured, 17 of which - for the first time. (invited paper)
