Abstract

We use a full coupled-channels method to calculate collisional properties of magnetically or optically trapped ultracold $^{6} Li .$ The magnetic-field dependence of the $s$ -wave scattering lengths of several mixtures of hyperfine states are determined, as are the decay rates due to exchange collisions. In one case, we find Feshbach resonances at $B = 0.08 T$ and $B = 1.98 T .$ We show that the exact coupled-channels calculation is well approximated over the entire range of magnetic fields by a simple analytical calculation.
