Abstract

The production of a quantum degenerate Bose-Fermi mixture with ⁸⁷Rb and ⁴⁰K atoms and the determination of cross-species scattering length were investigated. The observations of the spatial distribution of the gases after time-of-flight expansion confirmed the onset of degeneracy. It was found that the thermal relaxation rate of the ⁴⁰K cloud depended only on the collision rate with ⁸⁷Rb atoms. Multiple high-precision measurements including photoassociation and Feshbach spectroscopy were used in the experiment.
