摘要：对于预测p核丰度的网络计算来说，缺中子核（γ，n）光解离反应截面的知识是至关重要的。然而，迄今为止仅测量了单个横截面，即，人们几乎完全依赖于理论预测。虽然稳定同位素的横截面可以通过使用真实的光子的实验来获得，但所涉及的大部分反应都是从不稳定的核开始的。逆运动学中的库仑解离（CD）实验可能是扩展p过程网络计算实验数据库的关键。说明了检验CD法精度的方法。
Abstract.The knowledge of the cross sections for photodissociation reactions like e.g. (γ, n) of neutron deficient nuclei is of crucial interest for network calculations predicting the abundances of the so-called p nuclei. However, only single cross sections have been measured up to now, i.e., one has to rely nearly fully on theoretical predictions. While the cross sections of stable isotopes are accessible by experiments using real photons, the bulk of the involved reactions starts from unstable nuclei. Coulomb dissociation (CD) experiments in inverse kinematics might be a key to expand the experimental database for p-process network calculations. The approach to test the accuracy of the CD method is explained.
