Measurement of K X-ray fluorescence cross-sections and yields for 5.96Â keV photons

The Kα, Kβ, and total K X-rays fluorescence cross-sections, as well as the average fluorescence yields for six elements with 16⩽Z⩽23 have been measured at 5.96 keV. The areas of the Kα and Kβ spectral peaks, as well as the net peak areas, have been determined by a fitting process. Furthermore, the IKβ/IKα intensity ratios for these elements have been investigated. The K X-rays emitted by samples have been counted by a Si(Li) detector. Experimental values of the K X-ray fluorescence cross-sections, fluorescence yields, and the IKβ/IKα intensity ratios have been compared with theoretical values. In most cases, there is an agreement between the experimental and theoretical values within the standard uncertainties.
