原子质量评估的发展趋势和新进展

The Development Trends and New Advances in Atomic Mass Evaluation

  • 摘要: 原子质量评估(Atomic Mass Evaluation, AME)是一项收集和综合评价与原子质量相关(例如质谱术、衰变和核反应等)实验数据的重要工作,它被广泛认为是国际上权威可靠的原子质量信息来源。随着质量测量技术的不断发展,不仅测量的精度得到了显著提高,而且可测核素的范围也得到了扩大,同时揭示了许多奇特原子核的新现象。精确的质量数据为原子核结构、原子核反应以及核天体物理等基础核物理研究领域提供了不可或缺的参考。本工作对最新出版的原子质量数据评估AME2020进行了概述,并对当前主要质量测量实验装置的精度进行了检验,同时举例说明了重要实验数据。AME2020的发布对于广泛的科学研究和技术应用领域具有深远的实际影响。

     

    Abstract: The Atomic Mass Evaluation (AME) serves as a comprehensive source that collects and evaluates all experimental data related to atomic mass, including different techniques such as mass spectrometry, decay, and nuclear reactions. It is widely recognized as an authoritative and reliable repository of atomic masses in the world. In recent years, advancements in mass measurement technologies have significantly enhanced measurement precision, expanded the measurable range of nuclei, and unveiled new phenomena within exotic atomic nuclei. High-precision mass data provide indispensable references for fundamental nuclear physics research such as nuclear structure, nuclear reactions, and nuclear astrophysics. This article provides an overview of the latest Atomic Mass Evaluation, AME2020, and examines the accuracy of current major mass-measurements devices, and illustrates important experimental results. The release of AME2020 has profound practical implications for a wide range of scientific research and technological applications.
