给出了在200 - 600K温度范围内真正热化条件下，使用流动余辉/朗缪尔探针装置测量的αt，即O₂⁺、NH₄⁺和NO⁺与电子的离解复合系数。发现αt(O₂⁺)大致随T⁻⁰·⁷变化，这与先前关于αt(O₂⁺)和αe(O₂⁺)的脉冲余辉数据以及从离子阱数据推断出的αe(O₂⁺)值非常吻合。发现αt(NH₄⁺)大致随T⁻⁰·⁶变化。发现αt(NO⁺)大致随T⁻⁰·⁹变化，这与先前关于αt(NO⁺)的脉冲余辉数据相当一致。这些数据还与在脉冲余辉实验中测量的α₃(NO⁺)值以及从离子阱和合并束截面数据以及大气观测中得出的值进行了比较。
Measurements are presented for alpha t, the dissociative recombination coefficients with electrons of O2+, NH4+ and NO+ under truly thermalised conditions within the temperature range 200-600K using a flowing afterglow/Langmuir probe apparatus, alpha t(O2+) is found to vary as approximately T-0.7 in close accord with previous pulsed afterglow data for alpha t(O2+) and alpha e(O2+) and with values for alpha e(O2+) inferred from ion trap data. alpha t(NH4+) is found to vary as approximately T-.06. alpha t(NO+) is found to vary as approximately T-0.9 which is reasonably consistent with previous pulsed afterglow data for alpha t(NO+). These data are also compared with values of alpha 3(NO+) measured in a pulsed afterglow experiment and those derived from ion trap and merged beam cross section data and from atmospheric observations.
