Abstract
  • We report on the observation of ultracold heteronuclear Feshbach molecules. Starting with a ⁸⁷Rb Bose-Einstein condensate and a cold atomic gas of ⁸⁵Rb, we utilize previously unobserved interspecies Feshbach resonances to create up to 25,000 molecules. Even though the ⁸⁵Rb gas is nondegenerate, we observe a large molecular conversion efficiency due to the presence of a quantum degenerate ⁸⁷Rb gas; this represents a key feature of our system. We compare the molecule creation at two different Feshbach resonances with different magnetic-field widths. The two Feshbach resonances are located at 265.44±0.15   G and 372.4±1.3  G. We also directly measure the small binding energy of the molecules through resonant magnetic-field association.
