The obtained line profiles and linewidths of the Kα and Kβ transitions in Ni can be considered as the contribution of the satellite lines arising from the [KM] shake processes suggested by Deutsch et al [1] and Ito et al [2].

“…However, in the case of a double-crystal spectrometer with a higher order Bragg reflection, the instrumental function can be narrowed so that the correction for the window function remains simple (see [2,48] for details). Hence, we used a double-crystal spectrometer system (RIGAKU 3580EKI) with an end-window type X-ray tube with a rhodium target as anode material.…”

X-ray atomic properties of nickel were investigated in a singular approach that combines different experimental techniques to obtain new and useful reliable values of atomic fundamental parameters for X-ray spectrometric purposes and for comparison to theoretical predictions. We determined the mass attenuation coefficients in an energy range covering the L-and K-absorption edges, the K-shell fluorescence yield and the Kβ/Kα and Kβ 1,3/K α1,2 transition probability ratios. The obtained line profiles and linewidths of the Kα and Kβ transitions in Ni can be considered as the contribution of the satellite lines arising from the [KM] shake processes suggested by Deutsch et al. [1] and Ito et al. [2]. Comparison of the new data with several databases showed a good agreement but also discrepancies were found with existing tabulated values.

The characteristic radiation of copper Kα_1,2,3,4

et al. 2019

A characterization of the Cu K 1,2 spectrum is presented, including the 2p satellite line, K 3,4 , the details of which are robust enough to be transferable to other experiments. This is a step in the renewed attempts to resolve inconsistencies in characteristic X-ray spectra between theory, experiment and alternative experimental geometries. The spectrum was measured using a rotating anode, monolithic Si channel-cut double-crystal monochromator and backgammon detector. Three alternative approaches fitted five Voigt profiles to the data: a residual analysis approach; a peak-by-peak fit; and a simultaneous constrained method. The robustness of the fit is displayed across three spectra obtained with different instrumental broadening. Spectra were not well fitted by transfer of any of three prior characterizations from the literature. Integrated intensities, line widths and centroids are compared with previous empirical fits. The novel experimental setup provides insight into the portability of spectral characterizations of X-ray spectra. From the parameterization, an estimated 3d shake probability of 18% and a 2p shake probability of 0.5% are reported.

“…Several mechanisms such as shake-off and shake-up [6], conduction-band collective excitation [7], exchange [8], and final-state interactions [9] were suggested to account for this effect. However, recently, Deutsch et al [4], Hölzer et al [5], Anagnostopoulos et al [10], Chantler et al [11], and Ito et al [12,13] suggested that the line shapes in Kα 1,2 x-ray spectra could be accounted for by the diagram transition, and 3s, 3p, and 3d spectator-hole transitions. Ito et al [12] reported that the FWHM of the Kα 21 peak, which includes the satellite lines corresponding to the Kα 2 line, shows a different aspect from that of the Kα 11 peak, corresponding to a Kα 1 line, that may be ascribed to the L 2 -L 3 M 4,5 Coster-Kronig transitions.…”

The Kβ x-ray spectra of the elements from Ca to Ge have been systematically investigated using a highresolution antiparallel double-crystal x-ray spectrometer. Each Kβ 1,3 natural linewidth has been corrected using the instrumental function of this type of x-ray spectrometer, and the spin doublet energies have been obtained from the peak position values in Kβ 1,3 x-ray spectra. For all studied elements the corrected Kβ 1 x-ray lines FWHM increase linearly as a function of Z. However, for Kβ 3 x-ray lines this dependence is generally not linear in the case of 3d elements but increases from Sc to Co elements. It has been found that the contributions of satellite lines are considered to be [KM] shake processes. Our theoretically predicted synthetic spectra of Ca, Mn, Cu, and Zn are in very good agreement with our high-resolution measurements, except in the case of Mn, due to the open-shell valence configuration effect (more than 7000 transitions for diagram lines and more than 100 000 transitions for satellite lines) and the influence of the complicated structure of the metallic Mn.
