“…6͑b͒. The results are consistent with those in 21 was carried out for Sc 2 O 3 and the spectra seem to be consistent with those in Figs. 6 though the satellite structure seems to be weak compared with that of ScF 3 .…”

“…This fact suggests the large 2 p-3d interactions in ScF 3 suppress the absorption intensity to the t 2g state. The Sc 2 p absorption of Sc 2 O 3 was carried out by Elango et al 21 and its line shape is similar to that of ScF 3 , though its pre-edge structure is much weaker than that of ScF 3 . Figure 1͑b͒ shows TY spectrum, which corresponds to the absorption spectrum from F 1s core to F 2p components in the conduction bands, which is hybridized with Sc 3d components.…”

Threshold Al KLL Auger spectra of oxidized aluminium foils

“…The intensity of such a line might be expected to be weak for aluminium metal because of the free-electron-like nature of the material, but this should be less the case for the oxidized surface layer. Although it has been argued that the likelihood of spectator peaks becomes marginal as the degree of covalency increases, 59,62,63 these peaks have been observed for silicon dioxide. 10 It is possible that because Al(III)/O species tend to have a high density of unfilled states that have p-character 64 instead of 1s excitation to one particular unfilled p-like state, as the photon energy is increased an excitation to states of slightly higher energy occurs rather than the excess energy resulting in an Auger electron of higher kinetic energy.…”

Auger transition rates for Ar-like ions

“…If the scope is limited to the Ar-like ion case, the data for neutral Ar and only a few Ar-like ions of low atomic number were calculated [23,24] or measured [26,27]. However, atomic data for higher atomic numbers relevant to shorter X-ray pulse measurements are not readily available, to our knowledge.…”

“…Some atomic data for inner-shell exited states have been calculated [22][23][24] and measured [25][26][27]. If the scope is limited to the Ar-like ion case, the data for neutral Ar and only a few Ar-like ions of low atomic number were calculated [23,24] or measured [26,27].…”
