Abstract
State-selected total cross sections and thermal rate coefficients are computed for the HD + ortho-/para-H2 rotational energy transfer collision at low temperatures: 2 K ≲ T ≲ 300 K. A modified H2-H2 potential energy surface (PES) devised by Hinde is used for this pure quantum-mechanical dynamical computation. A comparison of the new results for the HD + ortho-/para-H2 scattering problem and previous calculations computed with the use of other older PESs is presented and discussed.
