title = "Expansion of a lithium gas in the BEC-BCS crossover",
abstract = "We report on experiments in 6Li Fermi gases near Feshbach resonances. A broad s-wave resonance is used to form a Bose-Einstein condensate of weakly bound 6Li 2 molecules in a crossed optical trap. The measured molecule-molecule scattering length of 170 -60 +100nm at 770 G is found in good agreement with theory. The expansion energy of the cloud in the BEC-BCS crossover region is measured. Finally we discuss the properties of p-wave Feshbach resonances observed near 200 Gauss and new s-wave resonances in the heteronuclear 6Li- 7Li mixture.",
