Using the quasi-classical trajectory method, the product rotational polarization of the ion-molecule reaction He D-2( ) 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(theta(r)), the distribution of the dihedral angle P(phi(r)), and the angular distribution of product rotational vectors in the form of polar plots in theta(r) and phi(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.
