Abstract
  • We investigate the production efficiency of ultracold molecules in bosonic ⁸⁵Rb and fermionic ⁴⁰K when the magnetic field is swept across a Feshbach resonance. For adiabatic sweeps of the magnetic field, our novel model shows that the conversion efficiency of both species is solely determined by the phase space density of the atomic cloud, in contrast with a number of theoretical predictions. In the nonadiabatic regime our measurements of the ⁸⁵Rb molecule conversion efficiency follow a Landau-Zener model.
