Expansion of a lithium gas in the BEC-BCS crossover
J. Zhang, E. G. M. Van Kempen, T. Bourdel +7
We report on experiments in Li Fermi gases near Feshbach resonances. A broad s-wave resonance is used to form a Bose-Einstein condensate of weakly bound Li molecules in…
P-wave Feshbach resonances of ultra-cold Li
J. Zhang, E. G. M. Van Kempen, T. Bourdel +7
We report the observation of three p-wave Feshbach resonances of Li atoms in the lowest hyperfine state . The positions of the resonances are in good agreement with theo…
Experimental Study of the BEC-BCS Crossover Region in Lithium 6
T. Bourdel, L. Khaykovich, J Cubizolles +6
We report Bose-Einstein condensation of weakly bound Limolecules in a crossed optical trap near a Feshbach resonance. We measure a molecule-molecule scattering length of$17…
Production of Long-Lived Ultracold Li2 Molecules from a Fermi gas
J. Cubizolles, T. Bourdel, S. J. J. M. F. Kokkelmans +2
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 r…
Measurement of interaction energy near a Feshbach resonance in a 6Li Fermi gas
T. Bourdel, J. Cubizolles, L. Khaykovich +4
We investigate the strongly interacting regime in an optically trapped Li Fermi mixture near a Feshbach resonance. The resonance is found at G in good agreement with…
