Abstract
We use the path-integral Monte Carlo technique and a recent high-accuracy six-dimensional potential to compute the cross second virial coefficients for all unlike pairs among the hydrogen isotopologues H2, D2, T2, HD, HT, and DT. Values are calculated from 15 K to 2000 K for these quantities where experimental information is almost completely absent. It is found that the commonly assumed arithmetic mean of the pure-component values does not provide a good approximation for the cross coefficients below approximately 50 K, especially for pairs containing H2.
