Abstract:

A previously developed theoretical model is used to describe the reactions D H2 DH H and H D2 HD D. Analytical expressions for the cross-sections are given and the permutational symmetry problem is briefly discussed. The results show a threshold region of relative kinetic energies, for which the reactions lead most probably to backward scattering in the center of mass system, the partial cross-sections with small relative angular momenta being dominant. At larger energies forward scattering is the most probable and the partial cross-sections with the highest relative angular momenta dominate. Comparison with experiments indicate agreement with the measured scattering directions, with the speed of HD product molecules and with the absolute value of differential cross-sections. The calculations predict an undetected forward scattering peak in the case of H D2, and show that the HD molecules from these reactions are mostly in low excited rotational states. Author
