本文讨论了超冷双组分费米气体中具有大且正散射长度a的短程组分间相互作用的三体过程。结果表明，在大多数情况下，三体复合的概率是质量比和a的普遍函数，并且与短程物理无关。我们还计算了原子-二聚体相互作用对应的散射长度。
We discuss three-body processes in ultracold two-component Fermi gases with short-range intercomponent interaction characterized by a large and positive scattering length a. It is found that in most cases the probability of three-body recombination is a universal function of the mass ratio and a, and is independent of short-range physics. We also calculate the scattering length corresponding to the atom-dimer interaction.
