CALCULATION OF INELASTIC ELECTRON-ATOM AND ELECTRON-MOLECULE COLLISION CROSS SECTIONS BY CLASSICAL METHODS,
Abstract
Use was made of Thomson's, Gryzinski's and Ochkur's classical methods for energy transfer in electronic collisions together with the quantum mechanical FranckCondon factor for the overlap of nuclear wave functions to compute inelastic electron-molecule collision cross sections. Specific application is to ionization and to direct and exchange electronic excitation. After first extending previous applications of the classical energytransfer methods to atoms, we make calculations for a number of processes involving air molecules (N2, N2(+), NO, O2, also CO). The results are applied to the near-threshold domain as well as to the overall behavior of the cross section. Agreement with the very few absolute experimental data available is to within better than a factor of 2-3. This must be regarded as encouraging when one considers that there exist hardly any experimental data on excitation and that quantum mechanical calculations would be prohibitively lengthy to carry out while the present calculations are very simple to perform.
