N2 - We report a theoretical study of Feshbach resonances in Li6 + Na23 and Li7 + Na23 mixtures at ultracold temperatures using accurate interaction potentials in a full quantum coupled-channel calculation. Feshbach resonances for l=0 in the initial collisional open channel Li6 (f=1 2, mf =1 2) + Na23 (f=1, mf =1) are found to agree with previous measurements, leading to precise values of the singlet and triplet scattering lengths for the Li 6,7 + Na23 pairs. We also predict additional Feshbach resonances within experimentally attainable magnetic fields for other collision channels.
