Extensive quantum mechanical coupled-channel and quasi-classical trajectory scattering calculations have been performed to obtain inelastic scattering cross sections for rovibrational transitions in orthoand para-H2 induced by He impact. Full rovibrational couplings and a reliable potential energy surface have been considered in the coupled-channel calculations. Cross sections for vibrational levels from v = 0 to 14 with rotational levels j = 0 to 30 were computed for kinetic energies between 10-4 and 3.5 eV, and the corresponding rate coefficients were calculated for the temperature range from 5 K to 10,000 K. The present rate coefficients are compared with recent results of Le Bourlot et al. (1999). Agreement is found to be less satisfactory for rovibrational transitions. A sample of astrophysical applications is also presented.
