Creating ultracold molecules by collisions with ultracold rare gas atoms in an optical trap

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 $\mu$ 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.
