摘要
Accurate three-dimensional quantum-mechanical (QM) scattering calculations have been performed for the S(D-1) + H-2 --> SH + H reaction at a collision energy of 2.24 kcal/mol. The shape of the rotational distribution and the forward/backward symmetry found in the total differential cross section (DCS) are characteristic of an insertion reaction. The QM DCS agrees with the experimental angular distribution. QM calculations show the bimodal behaviour of the experimental product translational energy distribution, in contrast with recent quasi-classical trajectory calculations.
