Collisional deactivation of the 6s' states of the Xe atom in the active medium of a high-pressure Ar — Xe laser

This is the authors' abstract. We don't add key points for this paper.

The method of absorption probing was used to investigate collisional deactivation of resonant (6 s '[1/2 1 0 ]) and metastable (6 s '[1/2] 0 0 ) states of the Xe atom in high-pressure Ar—Xe mixtures with low Xe concentrations. The rate constants were determined for the following plasma-chemical reactions: Xe(6 s ') + Ar → Xe*+ Ar [(1–2) × 10 -14 cm 3 s -1 ], Xe(6 s ') + 2Ar → ArXe* + Ar (less than 10 -35 cm 6 s -1 ), and Xe( 6 s ') + Xe + Ar → Xe 2 * + Ar [(3–3) × 10 -32 cm 6 s -1 ].
