Abstract
We report the observation of magnetic Feshbach resonances between 173Yb and 133Cs. In a mixture of Cs atoms prepared in the (f=3,mf=3) state and unpolarized fermionic 173Yb, we observe resonant atom loss due to two sets of magnetic Feshbach resonances around 622 and 702 G. Resonances for individual Yb nuclear spin components mi,Yb are split by its interaction with the Cs electronic spin, which also provides the main coupling mechanism for the observed resonances. The observed splittings and relative resonance strengths are in good agreement with theoretical predictions from coupled-channel calculations.
