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.

该项目旨在利用超灵敏加速器质谱测量对恒星核合成进行实验室研究。该项目将侧重于对恒星核合成建模中的开放问题至关重要的反应，即根本不存在数据或数据稀缺且不一致的反应;特别是与s和p过程相关的中子和带电粒子诱导反应，其中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，用于测试和改进理论预测。它们将非常有益于模拟恒星中各自的核合成过程，并有助于我们了解太阳系的元素丰度。
