Heteronuclear Feshbach Resonances in a Bose-Fermi Mixture of 40K and 87Rb
POSTER
Abstract
We have observed four magnetically tunable heteronuclear Feshbach resonances between fermionic 40K and bosonic 87Rb. Comparison of the measured positions of the resonances with theory identifies three as s-wave resonances and one as a p-wave resonance. We report on studies of inelastic loss of the mixture at these resonances. The observation of these resonances has allowed for a more precise determination of the background Rb-K interspecies scattering length.
