“…Furthermore, especially for the lighter lanthanoids, unusually strong double-electron excitations, 2p4d!5d 2 , [18,43] which are known to introduce errors in structural parameters, appear in the L 3 -edge k range. The high energies of the K edges for the lanthanoids of 39 (La) to 62 keV (Lu) result in a wide core-hole state, which significantly damps the EXAFS oscillations at high k. However, after correction the longer k range in the K-edge data enables better resolution of the Ln À O bond lengths.…”

“…Multielectron excitation [11][12][13][14][15][16][17][18] affects seriously the EXAFS signal at the L 3 -edge of Ce-absorption. After removing the multielectron excitation effect which was simulated with a Lorentzian function, the absorption curves were transferred to k space using the formula: k = (2m(E − E o )/ 2 ) 1/2 .…”

“…The leading resonance in the d coexcitation has been shown to maintain a fixed ratio to the K-edge resonance: the relation has been followed in the 4d MPE features from xenon far into the lanthanide series [22,24,25]. The 1s3d resonances in Kr and Rb in figure 5 also seem to keep the relation of the respective resonant 1s → 5p excitations at the K-edge.…”
