Phys. Rev. Lett. 91, 240401 (2003) [4 pages]Production of Long-Lived Ultracold Li2 Molecules from a Fermi Gas
J. Cubizolles1, T. Bourdel1, S. J. J. M. F. Kokkelmans1, G. V. Shlyapnikov1,2,3, and C. Salomon1 Received 1 August 2003; published 8 December 2003 We create weakly bound Li2 molecules from a degenerate two component Fermi gas by sweeping a magnetic field across a Feshbach resonance. The atom-molecule transfer efficiency can reach 85% and is studied as a function of magnetic field and initial temperature. The bosonic molecules remain trapped for 0.5 s and their temperature is within a factor of 2 from the Bose-Einstein condensation temperature. A thermodynamical model reproduces qualitatively the experimental findings. ©2003 The American Physical Society
