Abstract
We demonstrate and explain the coupling of several proximate Feshbach resonances in $^87}$Rb using radiofrequency (rf) radiation. We present accurate measurements of the resonances and observe the changes in the scattering properties that arise through the rf coupling. Our scattering theory analysis quantitatively agrees with the experimental data. We also present a simple interpretation of our results in terms of rf-coupled bound states interacting with the entrance channel threshold. Our work shows that rf radiation is useful as an extra degree of control in ultracold collisions.Citation
