Deexcitation of the 6s states of the Xe atom in high-pressure Ar–Xe mixtures

The processes of collisional deexcitation of the ³P₁ resonant and ³P₂ metastable states of the Xe atom in high-pressure Ar–Xe mixtures with a low concentration of Xe were investigated using an absorption probing method. Measurements were made of the effective rate constants of three-particle and two-particle quenching collisions of Xe*(³P_1,2) atoms with neutral particles.
