Abstract

We report a theoretical study of Feshbach resonances in $^{6}$ Li + $^{23}$ Na and $^{7}$ Li + $^{23}$ Na mixtures at ultracold temperatures using new accurate interaction potentials in a full quantum coupled-channel calculation. Feshbach resonances for $l=0$ in the initial collisional open channel $^6$ Li $(f=1/2, m_f=1/2) + ^{23}$ Na $(f=1, m_f=1)$ are found to agree with previous measurements, leading to precise values of the singlet and triplet scattering lengths for the $^{6,7}$ Li $+^{23}$ Na pairs. We also predict additional Feshbach resonances within experimentally attainable magnetic fields for other collision channels.
