Abstract
We have studied magnetic Feshbach resonances in an ultracold sample of Na prepared in the absolute hyperfine ground. W e report on the observation of three s-, eight d-, and three g-wave Feshbach resonances, including a more precis e determination of the two known s-wave resonances, and one s-wave resonance at a magnetic field exceeding 200 mT . Using a close-coupling calculation we have improved the sodium ground-state potentials by taking into account these new experimental data. In addition, a description of the molecular states leading to the Feshbach resonances in terms of the Asymptotic Bound-state Model is presented.Citation
