Several relaxation cross sections are calculated for Hg-H2 van der Waals complex.
These cross sections are calculated from exact close-coupling method.
Energy-dependent SBE cross sections are calculated for ortho- and para-H2 + Hg systems.
Viscosity and diffusion coefficients are calculated using Mason-Monchick approximation.
The results obtained by Mason-Monchick approximation are compared to the exact close-coupling results.
