| Popis: | The collision deactivation of the metastable 5s[3/2]2o(3P2) state of krypton atoms is studied by the absorption probe method in electron-beam-excited high-pressure Ar—Kr mixtures with a low krypton content. The rate constants of plasma-chemical reactions Kr* + Kr + Ar → Kr2* + Ar [(4.1±0.4)×10-33 cm6 s-1] and Kr* + 2Ar → ArKr* + Ar (less than 10-35 cm6 s-1) are measured for the first time and the rate constant of the reaction Kr* + Ar → products + Ar [(3.8±0.4)×10-15 cm3 s-1] is refined. |
