Abstract

We observe enhanced three-body recombination in a three-component Li6 Fermi gas attributable to an excited Efimov trimer state intersecting the three-atom scattering threshold near 895 G. From measurements of the recombination rate we determine the Efimov parameters κ* and η* for the universal region above 600 G which includes three overlapping Feshbach resonances. The value of κ* also predicts the locations of loss features previously observed near 130 and 500 G suggesting they are associated with a ground-state Efimov trimer near threshold. We also report on the realization of a degenerate three-component Fermi gas with approximate SU(3) symmetry.
