论文摘要
原子核是复合系统，在核反应过程中它们可能会动态激发。这种激发不仅与非弹性散射有关，而且还会影响其他反应过程，例如弹性散射和融合。耦合通道方法是一个框架，可以以统一的方式描述这些反应过程。它以碰撞核的地面和激发态来扩展系统的总波函数，并求解耦合的shrödinger方程以获得$ s $ matrix，从中可以从中构建几个横截面。这种方法已成为分析核反应实验数据的标准工具。在本文中，我们回顾了耦合通道方法的当前状态和最新发展。这包括微观耦合通道方法及其在聚类物理学中的应用，连续离散的耦合通道（CDCC）分手反应的方法（CDCC）方法，对重型离子subbarrier融合反应的半显微镜方法，对通道的核融合对核天线的反应和跨性别的反应，并构成了超级反应，并构成了反应性的分类，并取消了跨性别的分类。核。
Atomic nuclei are composite systems, and they may be dynamically excited during nuclear reactions. Such excitations are not only relevant to inelastic scattering but they also affect other reaction processes such as elastic scattering and fusion. The coupled-channels approach is a framework which can describe these reaction processes in a unified manner. It expands the total wave function of the system in terms of the ground and excited states of the colliding nuclei, and solves the coupled Shrödinger equations to obtain the $S$-matrix, from which several cross sections can be constructed. This approach has been a standard tool to analyze experimental data for nuclear reactions. In this paper, we review the present status and the recent developments of the coupled-channels approach. This includes the microscopic coupled-channels method and its application to cluster physics, the continuum discretized coupled-channels (CDCC) method for breakup reactions, the semi-microscopic approach to heavy-ion subbarrier fusion reactions, the channel coupling effects on nuclear astrophysics and syntheses of superheavy elements, and inclusive breakup and incomplete fusion reactions of weakly-bound nuclei.
