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 $P(\phi _r )$ 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.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
