Abstract
We observe Feshbach resonances in ultracold mixtures of and atoms in the and scattering channels. The positions and properties of the resonances are predicted and characterized using the semianalytic multichannel quantum-defect theory by Gao. Of particular interest, a number of broad entrance-channel-dominated resonances are identified, implicating exciting opportunities for studying a variety of interaction–dominated physics.
