Background: For its simplicity, the eikonal method is the tool of choice to analyze nuclear reactions at high energies ($E>100$ MeV/nucleon), including knockout reactions. However, so far, the effective interactions used in this method are assumed to be fully local.

考虑 eikonal 模型中光势的非定域性

背景：由于其简单性，eikonal 方法是分析高能核反应的首选工具（$乙>100$MeV/核子），包括敲除反应。然而，到目前为止，该方法中使用的有效相互作用被假定为完全局部的。
