Abstract (from CDS):

Rate coefficients for rotational transitions in HD induced by H2 impact for rotational levels of HD j <= 8 and temperatures 10 K <= T <= 5000 K are reported. The quantum mechanical close-coupling (CC) method and the coupled-states (CS) decoupling approximation are used to obtain the cross-sections employing the most recent highly accurate H2-H2 potential energy surface (PES). Our results are in good agreement with previous calculations for low-lying rotational transitions The cooling efficiency of HD compared with H2 and astrophysical applications are briefly discussed.
