利用最近获得的关于两体碰撞性质的知识，我们估计了$^{7}mathrm{Li}$、$^{23}mathrm{Na}$和$^{87}mathrm{Rb}$的双自旋极化超冷气体样品的三体重组率。我们发现只有重组导致最高的两体束缚态的形成是重要的。当角动量为零时，随着两体散射长度的绝对值的增加，最高界能级的速率也会增加。1996美国物理学会。
Using the knowledge of two-body collision properties that has recently become available, we estimate the three-body recombination rate for doubly-spin-polarized ultracold gas samples of $^{7}mathrm{Li}$, $^{23}mathrm{Na}$ and $^{87}mathrm{Rb}$ on the basis of the Jastrow approximation. We find that only recombination leading to the formation of the highest two-body bound states is important. The rate for the highest bound level with zero angular momentum is found to increase strongly with the absolute value of the two-body scattering length. extcopyright{} 1996 The American Physical Society.
