Lara, M. and Bohn, J. L. and Potter, D. E. and Soldan, P. and Hutson, J. M. (2006) 'Ultracold Rb-OH collisions and prospects for sympathetic cooling.', Physical review letters., 97 . p. 183201.
We compute ab initio cross sections for cold collisions of Rb atoms with OH radicals. We predict collision rate constants of order 10-11 cm3/s at temperatures in the range 10–100 mK at which molecules have already been produced. However, we also find that in these collisions the molecules have a strong propensity for changing their internal state, which could make sympathetic cooling of OH in a Rb buffer gas problematic in magnetostatic or electrostatic traps.
