连续壳模型是一种古老但最近复兴的方法，它跨越了核多体结构和核反应之间的边界。该方法是基于非厄米能量相关的有效哈密顿量。的形式主义，解释的解决方案，和实际执行的计算进行了详细讨论。传统的壳模型的结果完全再现的束缚态，共振参数和截面计算衰减状态。特别注意的是一个和两个核子反应通道，包括顺序和直接的两体衰变模式。给出了氦、氧同位素链反应截面的新计算方法，并与实验数据进行了比较。
The continuum shell model is an old but recently revived method that traverses the boundary between nuclear many-body structure and nuclear reactions. The method is based on the non-Hermitian energy-dependent effective Hamiltonian. The formalism, interpretation of solutions, and practical implementation of calculations are discussed in detail. The results of the traditional shell model are fully reproduced for bound states; resonance parameters and cross-section calculations are presented for decaying states. Particular attention is given to one- and two-nucleon reaction channels, including sequential and direct two-body decay modes. New calculations of reaction cross sections and comparisons with experimental data for helium and oxygen isotope chains are presented.
