论文摘要
天体物理反应率的确定需要不同的方法，具体取决于静水和爆炸性燃烧的条件。这里的重点是辐射性中子捕获反应的天体物理反应率。相关的核合成过程不仅涉及S过程，而且还涉及I-，R-和$γ$ - 过程，从核角度来看，中子和核的相对相互作用能的主要不同，以及所涉及核的核水平密度。重点放在低温和高温下反应之间的差异。说明了这些反应速率的预测和测量中的可能并发症，并解决了理论与实验之间的联系。
The determination of astrophysical reaction rates requires different approaches depending on the conditions in hydrostatic and explosive burning. The focus here is on astrophysical reaction rates for radiative neutron capture reactions. Relevant nucleosynthesis processes not only involve the s-process but also the i-, r- and $γ$-processes, which from the nuclear perspective mainly differ in the relative interaction energies of neutrons and nuclei, and in the nuclear level densities of the involved nuclei. Emphasis is put on the difference between reactions at low and high temperature. Possible complications in the prediction and measurement of these reaction rates are illustrated and the connection between theory and experiment is addressed.
