Abstract

We predict the presence of several magnetic Feshbach resonances in selected Zeeman sublevels of the isotopic pairs K(40)-Rb(87) and K(41)-Rb(87) at magnetic fields up to 1000 G. Positions and widths are determined combining a new measurement of the K(40)-Rb(87) inelastic cross section with recent experimental results on both isotopes. The possibility of driving a K-Rb mixtures from the weak to the strong interacting regime tuning the applied field should allow to achieve the optimal conditions for boson-induced Cooper pairing in a multi component K(40)-Rb(87) atomic gas and for the production of ultracold polar molecules.
