Abstract

We present 17 experimentally confirmed Feshbach resonances in optically trapped 85Rb. Seven of the resonances are in the ground-state channel (f,mf)=(2,+2)+(2,+2) and nine are in the excited-state channel (2,−2)+(2,−2). We find a wide resonance at high field in each of the two channels, offering possibilities for the formation of larger 85Rb 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 (2,+2)+(3,+3) spin mixture.
