Quenching of the resonance 5s(3P1) state of the krypton atomin collisions with krypton and argon atoms

Abstract

The processes of collision quenching of the resonance 5s[3/2]]01 (3P1) state of the krypton atom are studied by the absorption probe method in electron-beam-excited high-pressure Ar—Kr mixtures with a low content of krypton. The rate constants of plasmochemical reactions Kr* + Kr + Ar → Kr*2 + Ar [(4.40 ± 0.44) × 10-33 cm6 s-1], Kr* + 2Ar → ArKr* + Ar [(3.5 ± 0.9) × 10-36 cm6 s-1], and Kr* + Ar → products + Ar [(3.84 ± 0.38) × 10-15 cm3 s-1] are measured for the first time. The rate constants of similar reactions are refined for the metastable 5s[3/2]]02 (3P2) state.
