P-wave Feshbach resonances of ultracold ⁶Li

The three p-wave Feshback resonances of the ultracold 6Li atoms in the lowest hyperfine state f=1/2, were analyzed. The p-wave resonances were observed to have their origin in the same singlet bound state which leads to the s-wave Feshbach resonances located at 543 G and ~830 G. The lifetime of the cloud in the vicinity of the Feschbach resonances was studied and exhibited that, two- or three-body mechanisms are at play, depending on the spin states. As the reduction of inelastic losses close to a s-wave Feshbach resonance was observed as a key ingredient to fermionic superfluids, the formation of stable atom pairs requires a full description of decay mechanism at play close to a p-wave resonance
