“…But the radiative K X-ray transitions can be affected by the outer shell electronic distributions. In our previous studies, it was obtained that K shell fluorescence yields did not change by the outer shell electronic distributions in energy dispersive x-ray fluorescence systems [22][23]. For the L subshell level widths determination, K line (originates from the transitions between L and K shell) widths are used in the literature [20] since these lines cannot be affected by outermost shell electronic distributions in 3d metals where the valence electrons are free to move throughout the metallic structure.…”

The emission of X-rays in K and KLL Auger energy regions were analyzed for transition metals by using energy dispersive X-ray fluorescence (EDXRF) system. To acquire more information in this energy region, the semi-empirical determination of K, Auger line-widths and the L sub-shell level widths were performed. Since K shell is a core shell for transition metals and it is not easily be affected by valence shell electronic distributions, K shell fluorescence yields were used for the semi-empirical determinations. In the experiment, elemental form of transition metals were excited by 59.5 keV -rays from 241 Am annular source and the emitted X-ray photons were counted by Ultra-LEGe detector with a resolution of 150 eV at 5.9 keV. The obtained results were compared with the other studies in the literature.

“…The experimental values used in this work to calculate empirical and semiempirical data for elements from 25 Mn to 30 Zn relies on the published experimental data of Refs. []. The semiempirical method was based on both theoretical values, calculated using the relativistic Hartree–Slater theory taken from the work of Scofield for K β / K α intensity ratios, selected semiempirical values of Krause for the K‐shell fluorescence yield and to the experimental values of K β / K α intensity ratios and ω K , respectively.…”

It is known that zinc alloys with iron group metals have better corrosion resistance than pure zinc. Owing to the corrosion resistance of these alloys, Zn-Fe coatings are widely used in automotive industry and have excellent mechanical performance. In this work, we investigated the relationship between the changes in the measured X-ray fluorescence parameters (K β /K α , σ Kα and σ Kβ ) and the changes in the structural parameters such as microstrain or grain size values for Zn-Fe alloys that were prepared with different pH values. To explain these changes, the K α and K β X-ray production cross sections, and the K β /K α X-ray intensity ratio values were calculated by three different ways for the elemental forms of Zn and Fe. The structural parameters, such as microstrain and grain size, were also calculated. We expect that the outer shell electronic distribution affects the structural parameters of the produced Zn-Fe alloys, changing the measured K α and K β X-ray production cross sections, and the K β /K α X-ray intensity ratio values. We also show that Zn-Fe alloy mi nimum microstrain value corresponds to the maximum changes in K β X-ray production cross-section values of Fe and Zn.

The samples were excited by 22.69 keV X-rays from a 10 mCi Cd-109 radioactive point source and K X rays emitted by samples were counted by a high resolution Si(Li) solid-state detector coupled to a 4 K multichannel analyzer (MCA). The alloying effects on the X-ray fluorescence (XRF) parameters of Ti-Ni shape memory alloys (SMAs) were investigated. It is clearly observed that alloying effect causes to change in K shell XRF parameter values in Ti-Ni based SMAs for different compositions of x. Also, the present investigation makes it possible to perform reliable interpretation of experimental s Ka , s Kb and u K values for Ti and Ni in SMAs and can also provide quantitative information about the changes of K shell X-ray fluorescence cross sections and fluorescence yields of these metals with alloy composition.
