Laboratory studies of Nucleosynthesis via Accelerator Mass Spectrometry

本项目旨在应用超灵敏加速器质谱（AMS）测量进行恒星核合成的实验室研究。该项目将侧重于对恒星核合成建模中开放性问题至关重要的反应，即根本没有数据存在，或缺乏数据和差异的反应；特别是对于中子和带电粒子诱导的与-p过程相关的反应，需要极其灵敏的检测方法。关键核反应的新数据将与理论联系起来，用于检验和改进理论预测。它们将非常有利于模拟恒星各自的核合成过程，并有助于我们了解太阳系的元素丰度。

This project aims at laboratory studies of stellar nucleosynthesis applying ultra-sensitive accelerator mass spectrometry (AMS) measurements. The project will focus on reactions which are essential to open questions in modelling nucleosynthesis in stars, that is where no data exist at all, or are scarce and discrepant; in particular for neutron- and charged-particle induced reactions relevant to the s-and p-process where an extremely sensitive detection method is required. New data for key nuclear reactions will be connected with theory, for testing and improving theoretical predictions. They will be highly beneficial for modelling the respective nucleosynthesis processes in stars and for our understanding of the elemental abundance of our solar system.
