Efimov physics in an ultracold Bose-Fermi gas of ~${ }^{40}K$ and ${ }^{87}Rb$ atoms
ORAL
Abstract
We present measurements of Efimov physics in an ultracold Bose-Fermi gas of ${ }^{40}K$and ${ }^{87}Rb$ atoms near an interspecies Feshbach resonance. ~In particular, we measure loss rate coefficients for the trapped gas and find a resonance in the inelastic collisions of Feshbach molecules with~${ }^{87}Rb$ atoms.~However, we do not observe any E?mov-related resonances in the rates of inelastic collisions between three atoms.~
