Abstract The collision-induced dissociation of H2 in the (υ = 0, J = 0) internal state by H atoms was studied by three-dimensional quasi-classical trajectories on the Liu-Siegbahn-Truhlar-Horowitz ab initio potential energy surface. The dynamic threshold for dissociation was found to be essentially coincident with the energetic threshold. The dissociation cross sections were fitted to an excitation function and used to predict the rate constant for dissociation of H2 by H atoms by shock waves at very low interstellar densities.
