Abstract

Abstract 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 (ϕ_{r})

of dihedral angle and the distribution

P (θ_{r})

of angle between

k

and

j^{'}

have been presented at three different collision energies. Four generalized polarization-dependent differential cross-sections
