Calculations are made on the vibrational transition cross sections of e-H2, D2 scatterings in the energy range of 0 appox. 10eV. Both hybrid theory and the simultaneous vibrational and rotational adiabatic-nuclei approximation are employed in the calculation. It turns out that the latter approximation scheme yields better results than the hybrid theory approach when compared with experimental measurements on 0 yields v vibrational excitation. The resonance peaks of the elastic scattering and vibrational excitation cross section obtained from the vibrational and rotational adiabatic-nuclei approximation are quite broad between 2 approx. 3 eV, which are in good agreements with experimental data. This seems to indicate that the periods of the vibrational and rotational motions are comparable to each other and longer than the lifetime of the compound molecule. In general, the rate of the vibrational transition decreases as the quantum number change increases. The e-02 vibrational transition cross sections have also been explored with a semi-quantitative analysis.
