核素图评述与新设计

Review and a New Design of the Chart of Nucildes

核素图是原子核科学与技术领域基本的工具之一。基于原子核基本性质实验数据评估(The NUBASE2020 evaluation of nuclear physics properties)的公开数据制作了核素图,用颜色和文字展示了目前已知的基态原子核性质,包括同位素丰度、放射性衰变类型、半衰期、质量误差等实验信息。本工作评述了核素图数据可视化的最新进展,简述了核素版图的拓展历史和德国卡尔斯鲁厄核素图的发行历史,介绍了新版核素图的设计细节和未来展望,推荐了免费以及开源的核素图绘制程序。同时,还设计了印刷版核素图,计划随AME和NUBASE新版本发行同步更新,使它们成为展示NUBASE数据库简明信息的常规媒介。

The chart of the nuclides is one of the fundamental tools in nuclear science and technology.In this paper,we present a new two-dimensional chart of the nuclides,which displays up-to-date ground state nuclear properties such as isotopic abundances of stable nuclei,decay modes,half-life of radioactive nuclei,atomic mass error,and other experimental information extracted from the latest atomic mass evaluation AME2020 and NUBASE2020 evaluation of nuclear physics properties.We review the current status and trends in the visualization of nuclear charts,taking the Karlsruher Nuklidkarte as an example.We discuss the brief history and future perspectives of isotope discovery and nuclear chart publication,followed by the design details of our new chart of the nuclides.Additionally,we recommend free and open-source nuclear chart plotting software/websites.Our newly designed chart of the nuclides will be available in printed versions,including a wall chart and an A4-size folded chart for desktop usage.We plan to update the printed charts synchronously with the AME and NUBASE publications.This will ensure that the charts serve as a regular medium for the concise presentation of the NUBASE database.
