Production of Ultracold NH Molecules by Sympathetic Cooling with Mg.

Wallis, A.O.G. and Hutson, J.M. (2009) 'Production of Ultracold NH Molecules by Sympathetic Cooling with Mg.', Physical review letters., 103 (18). p. 183201.


We show that sympathetic cooling of NH molecules by Mg atoms has a good prospect of success. We carry out calculations on M-changing collisions of NH (3Σ-) molecules in magnetically trappable states with Mg, using a recently calculated potential energy surface. We show that elastic collision rates are much faster than inelastic rates for a wide range of fields at temperatures up to 10 mK and that the ratio increases for lower temperatures and magnetic fields.
