“…Due to advances in solid-state X-ray detectors, such as Si(Li) or intrinsic Ge detectors, much experimental data have been reported for K X-ray emission following radioactive decays, photon irradiation, and charged-particle impact. Recently, many experimental data were compiled, and recommended average values were proposed by Hamidani et al [ 1 ]. The

X-ray intensity ratio is frequently considered to be a characteristic quantity for each element, except in the cases where heavy-ion bombardment is used, leading to multiple ionizations [ 2 ].…”

Kα,β X-ray lines from photon excitation were measured in selected elements from Mg to Cu using a high-resolution double-crystal X-ray spectrometer with a proportional counter, and the Kβ/Kα intensity ratio for each element was obtained, after correcting for self-absorption, detection efficiency, and crystal reflectance. This intensity ratio increases rapidly from Mg to Ca but, in the 3d elements region, the increase becomes slower. This is related to the intensity of the Kβ line involving valence electrons. The slow increase of this ratio in the 3d elements region is thought to be due to the correlation between 3d and 4s electrons. Moreover, the chemical shifts, FWHM, asymmetry indices, and Kβ/Kα intensity ratios of the Cr compounds, due to different valences, were also investigated using the same double-crystal X-ray spectrometer. The chemical effects were clearly observed, and the Kβ/Kα intensity ratio was found to be compound-dependent for Cr.

FLUKA Simulations of Kβ/Kα Intensity Ratios of Copper in Ag–Cu Alloys

et al. 2021

View full text Add to dashboard Cite

The numerical simulations of Cu Kα and Cu Kβ fluorescence lines induced by Rh X-ray tube and by monoenergetic radiation have been presented. The copper Kβ/Kα intensity ratios for pure elements as well as for Ag–Cu alloys have been modeled. The results obtained by use of the FLUKA code, based on the Monte-Carlo approach, have been compared to available experimental and theoretical values. A visible relationship was found between the simulated Kβ/Kα intensity ratios and the copper content of the Ag–Cu alloy: as the Cu content increases, the Kβ/Kα coefficient decreases. The results can play role in elemental material analysis, especially in archaeometry.

The potential capabilities of the x‐ray spectral analysis method and the efforts of many researchers have ensured its widespread use in industry and scientific research. X‐ray fluorescence analysis (XRF) is one of the non‐destructive methods widely used to determine the chemical composition of automobile catalysts, solar panels, coins, jewelry, and so forth. In recent years, the problems of studying gold and silver objects of artistic value have attracted great interest. This paper presents a review of work on determining the chemical composition and thickness of single‐layer and multi‐layer coatings of artifacts and other objects of study with surfaces of complex configuration using the ratio of the intensities of characteristic x‐ray radiation of α‐ and β‐lines.
