“…In Table 3 we present the Kβ/Kα intensity ratios computed with the use of Equation (7) (Method1) and also computed using the intensities of the Lorentzian fits to the unbroadened spectra of Figure 1a,b. For comparison, we include the recommended value of Doudi et al from the recent compilation [45]. This recommended value corresponds to a weighted average of 12 experimental results that range from 0.1474(65) to 0.1692 (9).…”

We present relativistic ab initio calculations of fundamental parameters for atomic selenium, based on the Multiconfiguration Dirac-Fock method. In detail, fluorescence yields and subshell linewidths, both of K shell, as well as Kβ to Kα intensity ratio are provided, showing overall agreement with previous theoretical calculations and experimental values. Relative intensities were evaluated assuming the same ionization cross-section for the K-shell hole states, leading to a statistical distribution of these initial states. A method for estimating theoretical linewidths of X-ray lines, where the lines are composed by a multiplet of fine-structure levels that are spread in energy, is proposed. This method provides results that are closer to Kα1,2 experimental width values than the usual method, although slightly higher discrepancies occur for the Kβ1,3 lines. This indicates some inaccuracies in the calculation of Auger rates that have a higher contribution for partial linewidths of the subshells involved in the Kβ1,3 profile. Apart from this, the calculated value of Kβ to Kα intensity ratio, which is less sensitive to Auger rates issues, is in excellent agreement with recommended values.

“…The Kβ/Kα intensity ratios have been intensively studied since 1969. Daoudi et al [1] reports that after more than thousand measurements, 127 theoretical and experimental publications have been created in the last half century. The experimental measurements of X-ray spectra are crucial in examining theoretical models [2][3][4].…”

“…The study of Kβ/Kα intensity ratios can provide valuable information about the structure and chemical composition of materials. According to Daoudi et al [54] and Hamidani [55], this field has witnessed over a thousand measurements and has resulted in a substantial number of theoretical and experimental publications over the past fifty years. Therefore, it has a wide range of applications in various scientific fields and industries.…”

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

et al. 2021

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.
