在这项工作中，我给出了电子与O2分子碰撞产生的电子冷却速率、振动激发O2的产生速率和O2振动量子的产生频率随电子温度的函数的研究结果。利用修正的O2振动激发截面，计算了O2振动激发下的电子能量转移速率和冷却速率，并与解析表达式进行了拟合。这些新的解析表达式可供研究人员快速参考和精确的计算机建模，只需最少的计算。它还表明，目前公认的与O2中的转动跃迁有关的电子能量损失率必须降低13倍。
In this work I present the results of a study of the electron cooling rate, the production rates of vibrationally excited O2, and the production frequency of the O2 vibrational quanta arising from the collisions of electrons with O2 molecules as functions of the electron temperature. The electron energy transfer and cooling rates by vibrational excitation of O2 have been calculated and fitted to analytical expressions by use of the revised vibrationally excited O2 cross sections. These new analytical expressions are available to the researcher for quick reference and accurate computer modeling with a minimum of calculations. It is also shown that the currently accepted rate of electron energy loss associated with rotational transitions in O2 must be decreased by a factor of 13.
