天体物理学中的核质量

Nuclear Masses in Astrophysics

Christine Weber, Klaus Blaum, Hendrik Schatz

摘要:

在所有核基态性质中,原子质量对于N和Z的每种特定组合都是高度特定的,所获得的数据适用于各种物理主题。不稳定放射性核素质谱分析中最关键的问题之一是了解宇宙中元素形成的过程。为此,参与核合成的大量奇异核的精确原子质量值是大规模反应网络计算的关键输入数据之一。本文综述了核天体物理质谱学的最新进展。

英文摘要:

Among all nuclear ground-state properties, atomic masses are highly specific for each particular combination of N and Z and the data obtained apply to a variety of physics topics. One of the most crucial questions to be addressed in mass spectrometry of unstable radionuclides is the one of understanding the processes of element formation in the Universe. To this end, accurate atomic mass values of a large number of exotic nuclei participating in nucleosynthesis are among the key input data in large-scale reaction network calculations. In this paper, a review on the latest achievements in mass spectrometry for nuclear astrophysics is given.
