Query: Feshbach resonances in $^{23}\mathrm{Na}+$$^{39}\mathrm{K}$ mixtures and
  refined molecular potentials for the NaK molecule   We present a detailed study of interspecies Feshbach resonances of the
bosonic $^{23}\mathrm{Na}+$$^{39}\mathrm{K}$ mixture for magnetic fields up to
$750 \, \mathrm{G}$ 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
$^{23}\mathrm{Na}+$$^{40}\mathrm{K}$ to refine the singlet and triplet ground
state potentials of NaK and achieve a consistent description of Feshbach
resonances for both, the Bose-Bose mixture of
$^{23}\mathrm{Na}+$$^{39}\mathrm{K}$ as well as the Bose-Fermi mixture of
$^{23}\mathrm{Na}+$$^{40}\mathrm{K}$.
