使用l-不敏感的量子亏损理论，我们得到了一组普遍的属性，光谱和散射，共享的双原子系统与渐近货车德瓦尔斯相互作用，并具有零能量约束或准束缚状态的角动量l（B）。以Cs-133二聚体为例进行了研究。系统接近有一个绑定或准绑定状态的阈值进行了讨论。
Using an l-insensitive quantum defect theory, we derive a set of universal properties, both spectral and scattering, that are shared by diatomic systems with an asymptotic van der Waals interaction and having a zero-energy bound or a quasibound state of angular momentum l(b). The Cs-133 dimer is studied as an example. Systems that are close to having a bound or a quasibound state at the threshold are also discussed.
