标题： Electron capture rates in stars studied with heavy ion charge exchange reactions

摘要： 利用高能核-核反应的间接方法（此处，高能指$\sim$ 50 MeV/核子及以上）现在被常规用于提取对核天体物理有重要意义的信息。 这具有极高的相关性，因为参与恒星演化的许多核素是短寿命的。 因此，间接方法成为近期在主要核物理设施中进行的研究重点。 在这些方法中，重离子电荷交换被认为是一种有用的工具，可用于推断描述恒星中电子捕获速率以及双β衰变实验所需的Gamow-Teller矩阵元。 在本文的简要综述中，我基于一个简单的反应模型，为电荷交换反应提供理论指导。 显示英文摘要

摘要： Indirect methods using nucleus-nucleus reactions at high energies (here, high energies mean $\sim$ 50 MeV/nucleon and higher) are now routinely used to extract information of interest for nuclear astrophysics. This is of extreme relevance as many of the nuclei involved in stellar evolution are short-lived. Therefore, indirect methods became the focus of recent studies carried out in major nuclear physics facilities. Among such methods, heavy ion charge exchange is thought to be a useful tool to infer Gamow-Teller matrix elements needed to describe electron capture rates in stars and also double beta-decay experiments. In this short review, I provide a theoretical guidance based on a simple reaction model for charge exchange reactions.
