Precision Feshbach Spectroscopy of Ultracold Cs-2



C Chin, Vladan Vuletic, A J. Kerman, S G. Chu, Eite Tiesinga, P J. Leo, Carl J. Williams


We have observed > 60 magnetic field-induced Feshbach resonances in ultra-cold collisions of ground-state cesium atoms. The resonances have been detected using three different scattering processes: elastic collisions, inelastic collisions and radiative collisions. The observations have allowed us to improve upon the interaction potentials between two cesium atoms. Based on the relevant coupling scheme between the electron and nuclear spins, and orbital angular momenta of the nuclei, quantum numbers have been assigned to the observed resonances. Finally, we calculate the relevant collision parameters for cesium Bose-Einstein condensation experiments.
