P-wave Feshbach resonances of ultracold 6Li -: art. no. 030702

We report the observation of three p-wave Feshbach resonances of Li-6 atoms in the lowest hyperfine state f=1/2. The positions of the resonances are in good agreement with theory. We study the lifetime of the cloud in the vicinity of the Feshbach resonances and show that, depending on the spin states, two- or three-body mechanisms are at play. In the case of dipolar losses, we observe a nontrivial temperature dependence that is well explained by a simple model.
