The inelastic collisions in a fermionic 6Li gas system of different spin compositions near Feshbach resonances were studied. The two decay resonances at 550 and 680 G were shown by the spin mixture of the two lowest hyperfine states. It was found that these decay resonances were consistent with the predicted Feshbach resonances for elastic s-wave collisions.
