Abstract:

Critical evaluations of theories used for electron-molecule scattering calculation were made. The hybrid theory appears to be best suited for the calculation of e-CO vibrational transition cross sections. A reformulation of hybrid theory was made in terms of the total angular momentum representation. The vibrational transition cross sections of e-CO scattering were computed in the energy range of 0-10 eV, based on this reformulation. The agreement between the results of present calculation and the experimental measurements for 0-v vibrational transitions were reasonably good. Furthermore, the present calculations predicted the strong resonance peak at 1.4 eV in the 1-2 vibrational transition cross section. In general, the rate of vibrational excitations decreases as the change of vibrational quantum numbers increases. Author
