Abstract
We observe 69 interspecies Feshbach resonances including 13 elastic -wave resonances and 6 broad -wave resonances of atoms in different spin-state combinations at fields up to 600 G. Multichannel quantum-defect theory calculation is performed to assign these resonances and the results show perfect agreement with experimental values after improving input parameters. The observed broad - and -wave resonances display a fully resolved multiplet structure. They may serve as important simulators to nonzero partial-wave-dominated physics.
