Total electron scattering and electronic state excitations cross sections for O₂, CO, and CH₄

Available electron collision cross section data concerning total and elastic scattering, vibrational excitation, and ionization for O 2 , CO, and CH 4 have been critically reviewed, and a set of cross sections for modeling of planetary atmospheric behavior is recommended. Utilizing these recommended cross sections, we derived total electronic state excitation cross sections and upper limits for dissociation cross sections, which in the case of CH 4 should very closely equal the actual dissociation cross section.
