Abstract : Vibrational excitation in the system He + H2 is studied theoretically by considering H2 as a rotating Morse Oscillator. The anharmonicity of molecular vibration is found to have only a small effect on the 0 to 1 transitions. Vibrational transition probabilities are also found to be insensitive to the rotational energy of the diatom. Following the approach of Mies and Shuler, based on the modified wave number approximation, three-dimensional transition probabilities are calculated from one-dimensional results and the steric factor obtained as a function of the collision energy. Franck-Condon factors for the transitions N2, C triplet Pi(u) to B triplet Pi(g) and CN, B doublet Sigma(+) to X doublet Sigma(+) have been calculated by the method of Chang and Karplus. (Author)
