摘要：

We report on the observation of six large Feshbach resonances in a Fermi-Bose mixture of Li-6 and Rb-85 atoms. Near the resonances, both the elastic and inelastic collision rates are enhanced, and this results primarily in the loss of Li-6 from an optical dipole trap since it is less massive and less confined than its Rb-85 collision partner. We interpret our experimental data using a coupled-channels calculation which fully characterizes the ground-state scattering properties in any combination of spin states.
