论文摘要
我们用17B-N-N三体系统描述了19b，其中两体子系统17B-N和N-N是未接近统一限制的未结合（虚拟）状态。 19b基态的能量得到很好的再现，并预测了两个低洼的共振。讨论了他们与Efimov物理学的最终联系。可以扩展该模型以描述20,21B中最近发现的共振状态。
We describe 19B in terms of a 17B-n-n three-body system, where the two-body subsystems 17B-n and n-n are unbound (virtual) states close to the unitary limit. The energy of 19B ground state is well reproduced and two low-lying resonances are predicted. Their eventual link with the Efimov physics is discussed. This model can be extended to describe the recently discovered resonant states in 20,21B.
