Quantum-Mechanical State-to-State Differential Cross Sections for the Reaction F +H2→ H + HF

This communication presents the first nonperturbative quantum-mechanical calculation for state-resolved angular differential cross sections for a chemical rearrangement for which experimental results are available. The reaction studied, F + ${\mathrm{H}}_2$ → H + HF, is an important prototype for understanding reaction dynamics and is one of the few for which comparisons of experiment and theory are possible. The significant features of the state-to-state angular distributions for this reaction observed experimentally are reproduced by this study.
