研究了轻核中软偶极子模式的非弹性电子散射激发。我证明，在即将到来的电子-离子对撞机的条件下，散射截面与实光子的散射有直接关系。探讨了电子散射相对于其他电磁探针的优点。采用少体模型研究了直接破碎的响应函数。讨论了对末态相互作用的依赖。对直接分解模型和集体分解模型进行了比较。这项调查的结果对于计划在GSI和RIKEN设施中的电子-离子对撞机是重要的。
The excitation of soft dipole modes in light nuclei via inelastic electron scattering is investigated. I show that, under the proposed conditions of the forthcoming electron-ion colliders, the scattering cross sections have a direct relation to the scattering by real photons. The advantages of electron scattering over other electromagnetic probes is explored. The response functions for direct breakup are studied with few-body models. The dependence on final-state interactions is discussed. A comparison between direct breakup and collective models is performed. The results of this investigation are important for the planned electron-ion colliders at the GSI and RIKEN facilities.
