本文综述了库仑势垒附近能量（E< 10 MeV/核子）的轻（A< 20）放射性射弹聚变反应的现状，着重介绍了近十年来的测量结果。弹性散射数据（提供总反应截面信息）和破碎渠道所涉及的系统，展示这些和融合通道之间的关系，也进行了审查。相似性和差异的行为的融合和总反应截面数据晕核，弱约束，但不那么奇异的弹丸，和强约束系统进行了讨论。库仑势垒附近的聚变激发函数的行为的一个差异似乎出现在中子晕和质子晕系统之间。电荷的作用进行了研究，通过比较聚变激发函数，适当缩放，为不同的中子和质子丰富的系统。可能的物理解释所观察到的差异也进行了审查。
The present status of fusion reactions involving light (A< 20) radioactive projectiles at energies around the Coulomb barrier (E< 10 MeV per nucleon) is reviewed, emphasizing measurements made within the last decade. Data on elastic scattering (providing total reaction cross section information) and breakup channels for the involved systems, demonstrating the relationship between these and the fusion channel, are also reviewed. Similarities and differences in the behavior of fusion and total reaction cross section data concerning halo nuclei, weakly-bound but less exotic projectiles, and strongly-bound systems are discussed. One difference in the behavior of fusion excitation functions near the Coulomb barrier seems to emerge between neutron-halo and proton-halo systems. The role of charge has been investigated by comparing the fusion excitation functions, properly scaled, for different neutron- and proton-rich systems. Possible physical explanations for the observed differences are also reviewed.
