Abstract
We report on the observation of six large Feshbach resonances in a Fermi-Bose mixture of and atoms. Near the resonances, both the elastic and inelastic collision rates are enhanced, and this results primarily in the loss of from an optical dipole trap since it is less massive and less confined than its 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.
