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…
