Determination of the temperature dependence of the rate constant representing quenching of metastable iodine atoms by iodine molecules

The rate constant of quenching of the 5p^{5 2}P_1/2 level of atomic iodine by J₂ molecules was determined in the gas temperature range 293–1000°K. The experimental results fitted the approximate formula k(T) = 8x10^–11exp(–4.4×10^–3T) cm³/sec.
