提出了复杂能量平面的壳模型的实现。该方法中使用的表示由复杂能量平面上的束缚单粒子态、伽莫夫共振和散射波组成。评估双粒子共振，并分析它们在单粒子自由度方面的结构。研究发现，双粒子共振主要建立在束缚态和伽莫夫共振的基础上，但散射态的贡献也很重要。
An implementation of the shell-model to the complex energy plane is presented. The representation used in the method consists of bound single-particle states, Gamow resonances and scattering waves on the complex energy plane. Two-particle resonances are evaluated, and their structure in terms of the single-particle degrees of freedom is analyzed. It is found that two-particle resonances are mainly built upon bound states and Gamow resonances, but the contribution of the scattering states is also important.
