  Motivated by the prospect of observing Efimov and Bose polaron physics in
ultracold mixtures of bosonic atoms with large mass imbalance, this work
investigates the magnetic Feshbach resonances between $^{7}\text{Li}$ and
$^{133}\text{Cs}$. The resonances are predicted at the 1 gauss level using the
model of Pires et al. [Phys. Rev. A, 90, 012710] obtained from experimental
observations of resonances between $^{6}\text{Li}$ and $^{133}\text{Cs}$. It is
found that a few resonances in a practical range of magnetic field intensity
could be used to tune the scattering length between $^{7}\text{Li}$ and
$^{133}\text{Cs}$ atoms. Opportunities for observing Efimov and Bose polaron
physics are discussed.
