p-wave Feshbach Molecules

We present evidence for the production and detection of molecules using a p-wave Feshbach resonance between $^{40}$K atoms. We have measured the binding energies and lifetimes for these molecules. We find that the binding energies scale linearly with magnetic field near the resonance. At magnetic fields above the resonance we detect quasi-bound molecules with lifetimes set by the tunneling rate through the centrifugal barrier. We discuss the possibility of using a p-wave Feshbach resonance to study BCS-BEC crossover physics with finite angular momentum pairing.
