Abstract
We present 17 experimentally confirmed Feshbach resonances in optically trapped Rb. Seven of the resonances are in the ground-state channel and nine are in the excited-state channel . We find a wide resonance at high field in each of the two channels, offering possibilities for the formation of larger Rb condensates and studies of few-body physics. A detailed coupled-channel analysis is presented to characterize the resonances and also provides an understanding of the inelastic losses observed in the excited-state channel. In addition we have confirmed the existence of one narrow resonance in a spin mixture.
