3dspectator hole satellites of the CuKβ1,3andK

Temperature-induced obliteration of sub-oxide interfaces in amorphous GeO

“…The measurements were carried out in partial fluorescence yield detection [14] using a crystal spectrometer in Rowland geometry with a Si553 spherically bent analyzer [15]. The analyzer energy of the spectrometer was set to the maximum of the Ge K a1 fluorescence line.…”

Benchmark results and theoretical treatments for valence-to-core x-ray emission spectroscopy in transition metal compounds

“…To this end, each full spectrum was fit to a series of pseudo-Voigt functions and a constant background using the Blueprint XAS package. [70,71] In addition to the main Kβ 1,3 and valence features, we include extra curves to model the multi-electron excitation peaks (KLβ) above the Fermilevel [72][73][74] and the radiative Auger satellites [73] Representative results of this procedure are shown in section IV.A, below.…”

“…All these interpretations suggest that the intensity of the Kβ line is not dependent on either the projectile kind or energy, but depends only on the subsequent relaxation process. On the other hand, several authors [51][52][53][54] state that in the Kβ region, the main mechanism responsible for this structure is a 3d spectator hole transition. Particularly, measurements carried out recently with photon excitation [53,54] in copper, where the exchange interactions are less important, indicate that the structure appearing in the Kβ region presents an intensity dependent on the excitation energy near the double ionization edge, supporting the last interpretation.…”

The use of different particles as excitation sources could help to reveal the nature of this spectral region, since a different particle has a different probability to create a double vacancy state.…”
