摘要
We present a multichannel quantum-defect theory for magnetic Feshbach resonances in the interaction of two heteronuclear group-I atoms. The theory provides a unified and a uniform description of resonances in all partial waves and enables the characterization of a large number of resonances in terms of very few parameters. For the sample system of Li-6 K-40, we present descriptions of all resonances in aa, ab, and ba channels, in partial waves s (l = 0) through h (l = 5), and in a magnetic field of 0-1000 G. All resonances, including those in nonzero partial waves, are fully characterized using the newly developed parametrization of Gao [Phys. Rev. A 84, 022706 (2011)].
