Abstract

We study collisions of para-H $_{2}$ with five rare gas atomic species (He, Ne, Ar, Kr and Xe) over the range from 1 K to 1 $μ$ K and evaluate the feasibility of sympathetic cooling H $_{2}$ with ultracold ground state rare gas atoms co-trapped within a deep optical trap. Collision cross-sections over this large temperature range show that all of these species could be used to cool H $_{2}$ to ultracold temperatures and that argon and helium are the most promising species for future experiments.
