Popis:	The product energy distribution for the reaction A + B→AB+ + e (where A and B are atoms) is considered on a theoretical basis. Due to the large mass ratio of the products, conservation of energy and momentum largely determine the product energy distribution without requiring a detailed knowledge of the mechanics of the collision complex. Assuming a hard‐sphere line‐of‐center model, it is shown that AB+ would be produced with thermal translational and rotational energies. The sum of the average AB+ vibration and electron translation energies is kT. Detailed balancing is used to estimate the partitioning of this kT energy between the AB+ vibration and electron kinetic degrees of freedom. Calculations are presented showing the dependence of electron energy on reaction temperature and the AB+ vibrational frequency. The electron must always be produced at less than thermal energies. For the reaction N + O→NO+ + e at 6500°K it is estimated the electron would be produced at 1800°K.
