摘要

可靠的基本参数是准确的x射线荧光分析钠的必要条件。这项工作提出了更新的实验值与可靠的不确定度的钠k壳基本参数，如：荧光产额，光电离截面，和俄歇产额。采用物理校准装置和氮化硅膜上的薄NaCl层，采用整体测定方法来减少不确定度。新值代表了对数据库中广泛使用的值的重大改进。所有数据均可通过Zenodo获得，以支持科学和工业应用中的精确钠定量。

Experimental determination of the sodium K-shell atomic fundamental parameters for X-ray spectroscopy

Reliable fundamental parameters are essential for accurate X-ray fluorescence analysis of sodium. This work presents updated experimental values with reliable uncertainties for sodium K-shell fundamental parameters such as: fluorescence yield, photoionization cross sections, and Auger yields. Using a physically calibrated setup and a thin NaCl layer on a silicon nitride membrane, a holistic determination approach was applied to reduce uncertainties. The new values represent a significant improvement on the ones widely used in databases. All data are available via Zenodo to support precise sodium quantification in scientific and industrial applications.
