Phys. Rev. Lett. 91, 250401 (2003) [4 pages]Observation of Bose-Einstein Condensation of MoleculesReceived 27 November 2003; published 15 December 2003 We have observed Bose-Einstein condensation of molecules. When a spin mixture of fermionic 6Li atoms was evaporatively cooled in an optical dipole trap near a Feshbach resonance, the atomic gas was converted into 6Li2 molecules. Below 600 nK, a Bose-Einstein condensate of up to 900 000 molecules was identified by the sudden onset of a bimodal density distribution. This condensate realizes the limit of tightly bound fermion pairs in the crossover between BCS superfluidity and Bose-Einstein condensation. © 2003 The American Physical Society URL:
