Theoretical study of the stereodynamics of the He+HD⁺ reaction

This paper investigates the stereodynamics of the reaction He+HD^+ by the quasi-classical trajectory (QCT) method using the most accurate AQUILANTI surface Aquilanti et al 2000 Mol. Phys. 98 1835. The distribution P(\phi _r ) of dihedral angle and the distribution P(\theta _r ) of angle between k and j' have been presented at three different collision energies. Four generalized polarization-dependent differential cross-sections (2\pi / \sigma ) d\sigma _00 /d\omega _t ), (2\pi / \sigma )(d\sigma _20 /d\omega _t ), (2\pi / \sigma )(d\sigma _22 + / d\omega _t ), (2\pi / \sigma )(d\sigma _21 - /d\omega _t ) are also calculated. Some interesting results are obtained from the comparison of the stereodynamics of the title reaction at different collision energies.
