Tuning P-Wave Interactions in an Ultracold Fermi Gas of Atoms



C A. Regal, J L. Ticknor, J L. Bohn, D S. Jin


We have measured a p-wave Feshbach resonance in a single-component, ultracold Fermi gas of 40K atoms. We have used this resonance to enhance the normally suppressed p-wave collision cross-section to values larger than thebackground s-wave cross-section between 40K atoms in different spin-states. In addition to the modification of two-body elastic processes, the resonance dramatically enhances three-body inelastic colulsional loss.
