Phys. Rev. A 78, 010701(R) (2008) [4 pages]Feshbach resonances in ultracold 6,7Li+23Na atomic mixtures
We report a theoretical study of Feshbach resonances in 6Li+23Na and 7Li+23Na 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 6Li(f=1∕2,mf=1∕2)+23Na(f=1,mf=1) are found to agree with previous measurements, leading to precise values of the singlet and triplet scattering lengths for the 6,7Li+23Na pairs. We also predict additional Feshbach resonances within experimentally attainable magnetic fields for other collision channels. © 2008 The American Physical Society URL:
