摘要: In a dc glow discharge in oxygen, the concentrations of minor components O2(a1Δg), O2(b1 Σg), O3, O(1D), as well nagative ions and electrons have been measured. Balance equations derived which describe satisfactorily stationary these functions gas pressure current. For first time, rate constants important aeronomical reactions (a) O− + O2(a1Δg) O3 e, (b) O2− 2O2 e (c) +O measured temperature T mean energies Ei electron E6: Ka = (2.5 ± 0.5) · 10−9 (T/300)4 0.4· (Ei/0.04)−2.6 0.4 cm3/s for 385−605 K 0.10 − 0.66 eV; Kb (1.0 0.3) 10−10 (T/300)−2 0.5 (Ei/0.04)0.23 0.05 330−605 0.09 1.5 Kc Ee 0.8÷5 eV.
