() 和 () 光核反应截面的测量与多种核合成场景相关，从原始大爆炸到恒星燃烧和 p 过程。随着单能射线束设施的出现和检测方法的改进，光核反应截面的研究在过去 20 年中取得了稳步发展。固体目标中光子诱发反应的带电粒子检测主要通过硅带探测器实现，而时间投影室则用于测量活性气体目标。这篇综述跟踪了带电粒子检测方法的演变，并重点介绍了最近使用单能射线束进行的 Li()He 和 O()C 截面测量。
Measurements of () and () photonuclear reaction cross sections are relevant for several nucleosynthesis scenarios, from the primordial Big Bang, to stellar burning, and the p-process. Studies of photonuclear reaction cross sections marked a steady development in the last 20 years with the advent of mono-energetic-ray beam facilities and improved detection methods. Charged-particle detection from photon-induced reactions in solid targets is mainly achieved with silicon-strip detectors, while time projection chambers were developed for measurements with active gas targets. This review tracks the evolution of charged-particle detection methods and highlights recentLi()He andO()C cross section measurements using mono-energetic-ray beams.
