Abstract
We present a detailed study of interspecies Feshbach resonances of the bosonic mixture for magnetic fields up to in various collision channels. A total of fourteen Feshbach resonances are reported, as well as four zero crossings of the scattering length and three inelastic two-body loss features. We use the observed magnetic field locations of the resonant features together with the known data on to refine the singlet and triplet ground state potentials of NaK and achieve a consistent description of Feshbach resonances for both, the Bose-Bose mixture of as well as the Bose-Fermi mixture of .
