23Na +39K Feshbach resonances paper published!

 In our new paper we present a detailed study of interspecies Feshbach resonances in a mixture of bosonic 23Na+39K. We identified a total of 14 Feshbach resonances, as well as four zero crossings of the scattering length and three inelastic two-body loss features. Based on our measurements and previously existing data on fermionic 23Na+40K, we also refined the singlet and triplet ground-state potentials of NaK.
