标题： Scaling limit of virtual states of triatomic systems

摘要： 对于包含三个相同原子的系统，计算了$s-$波虚态能量对弱结合二聚体和三聚体结合能的依赖关系，其形式为一个通用标度函数。 该标度函数来自于具有成对狄拉克-δ相互作用的可重整化三体模型。 还讨论了三聚体虚态出现的阈值条件。 显示英文摘要

摘要： For a system with three identical atoms, the dependence of the $s-$wave virtual state energy on the weakly bound dimer and trimer binding energies is calculated in a form of a universal scaling function. The scaling function is obtained from a renormalizable three-body model with a pairwise Dirac-delta interaction. It was also discussed the threshold condition for the appearance of the trimer virtual state.
