Abstract
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.
