The classical trajectory study method has been used to investigate the effects of H/sub 2/ vibration on inelastic scattering in the system He+H/sub 2/. Specifically, earlier calculations which included H/sub 2/ vibration have been repeated using the rigid rotor approximation. In addition, new calculations, both with and without H/sub 2/ vibration, have been performed at total collision energies of 5 and 10 eV. It is found that H/sub 2/ vibration exerts a noticeable effect at energies above 5 eV; however, even at 10 eV, the rigid rotor approximation works well for the most important transitions. (AIP)
