标题： The Photodissociation of $^8B$ and the Solar Neutrino Problem

摘要： 从库仑离解实验中提取光离解截面$^8B$的研究进行了探讨。 对 E1、E2 和 M1 多极性对破裂的贡献进行了仔细研究。 与最近实验的数据进行了比较。 结果表明，与太阳中微子问题相关的辐射捕获截面$^7Be(p,\ \gamma)^8B$的提取不会明显受到库仑再加速的影响。 为此使用了一个非微扰模型。 重点放在了计划在圣母大学、理化学研究所（日本）和 GSI（德国）进行的未来实验的前景上。 还对非弹性电子散射中“光子点”过程的总产额进行了分析。 显示英文摘要

摘要： The extraction of the photodissociation cross sections of $^8B$ from Coulomb dissociation experiments is investigated. A careful study is done on the contributions of the E1, E2 and M1 multipolarities to the breakup. A comparison with the data of a recent experiment is performed. It is shown that the extraction of the radiative capture cross sections $^7Be(p,\ \gamma)^8B$ which are relevant for the solar neutrino problem is not affected appreciably by Coulomb reacceleration. A non-perturbative model is used for the purpose. Emphasis is put on the perspectives for future experiments which are planned at the University of Notre Dame, RIKEN (Japan), and GSI (Germany). An analysis of the total yields of ``photon-point" processes in inelastic electron scattering is also done.
