Abstract
A reactive scattering infinite order sudden approximation presented earlier is applied to the H+H2 exchange reaction. Detailed results for both differential and integral reactive cross sections are presented and compared with accurate close coupling results obtained earlier by Kuppermann and Schatz. Qualitative agreement is obtained for detailed state‐to‐state cross sections and more quantitative agreement is demonstrated for cross sections summed over final states.
