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

Abstract

The K α , K β , 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 K α and K β spectral peaks, as well as the net peak areas, have been determined by a fitting process. Furthermore, the I K β / I K α 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 I K β / I K α 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.
