Abstract
The authors present a new technique for characterizing the scattering and Feshbach resonances of two different species atoms. A single ultracold Na and Cs atom are trapped in the same optical tweezer and cooled to the ground state. The interactions of the two atoms modify their motional trapping frequencies, which are measured spectroscopically and used to characterize the scattering properties.
