本文研究了三体或四体系统在其所有子系统都不被约束的情况下被约束的耦合常数域。区域大小的限制来自Hall- Post不等式的一个变体，它将$N$体与$(N-1)$体在给定耦合下的能量联系起来。简述了晕核和超核的可能应用。
We study the domain of coupling constants for which a 3-body or 4-body system is bound while none of its subsystems is bound. Limits on the size of the domain are derived from a variant of the Hall--Post inequalities which relate $N$-body to $(N-1)$-body energies at given coupling. Possible applications to halo nuclei and hypernuclei are briefly outlined.
