The paper presents a problem in computations of X-ray fluorescence cross-sections, shell/sub-shell fluorescence yields, Coster–Kronig yields, vacancy alignment, etc. from X-ray fluorescence (XRF) studies. While using barn/atom as a unit for cross-sections if the atomic masses are not considered it causes a discrepancy in the measured cross-section, yield and alignment values. Most of the earlier publications are being quoted where such an oversight has occurred and discrepancy is evident.
► Manuscript gives basic formulation for measurements of fluorescent X-ray intensities. ► Most publications ignored the fact that use of barn/atom units for cross-sections requires atomic masses. ► Published experimental results higher by a factor ≥2 or less by factor 1/MK. ► Inspection of published data on XRF parameters needed.
