The processes of collision quenching of the resonance 5s[3/2]]{sup 0}{sub 1} ({sup 3}P{sub 1}) 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 {yields} Kr*{sub 2} + Ar [(4.40 {+-} 0.44) x 10{sup -33} cm{sup 6} s{sup -1}], Kr* + 2Ar {yields} ArKr* + Ar [(3.5 {+-} 0.9) x 10{sup -36} cm{sup 6} s{sup -1}], and Kr* + Ar {yields} products + Ar [(3.84 {+-} 0.38) x 10{sup -15} cm{sup 3} s{sup -1}] are measured for the first time. The rate constants of similar reactions are refined for the metastable 5s[3/2]]{sup 0}{sub 2} ({sup 3}P{sub 2}) state. (laser spectroscopy)
