Phys. Rev. Lett. 102, 020405 (2009) [4 pages]Ultracold Heteronuclear Fermi-Fermi MoleculesSee Also: Erratum Received 7 October 2008; published 15 January 2009 We report on the first creation of ultracold bosonic heteronuclear molecules of two fermionic species, 6Li and 40K, by a magnetic field sweep across an interspecies s-wave Feshbach resonance. This allows us to associate up to 4×104 molecules with high efficiencies of up to 50%. Using direct imaging of the molecules, we measure increased lifetimes of the molecules close to resonance of more than 100 ms in the molecule-atom mixture stored in a harmonic trap. © 2009 The American Physical Society URL:
