Stereodynamics of the He+D₂⁺→HeD⁺+D Reaction on the PALMIERI Surface

Using the quasi-classical trajectory method, the product rotational polarization of the ion-molecule reaction He+D₂⁺ has been calculated at different collision energies on the PALMIERI potential energy surface Palmieri et al. Mol. Phys. 98 (2000) 1835. The distribution angle between k and j', P(θ_r), the distribution of the dihedral angle P(Φ_r), and the angular distribution of product rotational vectors in the form of polar plots in θ_r and Φ_r are calculated. In addition, four polarization-dependent differential cross sections are also presented in the center-of-mass frame, respectively. The results indicate that the rotational polarization of the product HeD⁺ presents different characters for different collision energies. These discrepancies may be ascribed to the different collision energies and constructions of the potential energy surface.
