3d spectator hole satellites of the CuKβ1,3 and Kβ2,5 emission spectrum -: art. no. 022508

The intensity evolution of the Cu Kbeta(1,3) and Kbeta(2,5) emission spectra is measured as a function of excitation energy using resonant inelastic x-ray scattering spectroscopy. The contribution of (1s3d) under bar shake satellites to the Cu Kbeta(1,3) as well as to the Cu Kbeta(2,5) emission spectrum is extracted. Both emission spectra indicate an additional contribution of ($) under bar 1s3d shake satellites. The intensity evolution of the shake satellites from threshold to saturation is compared to the Thomas model and shows a similar saturation behavior as found for the Cu Kalpha(1,2) (1s3p) under bar shake satellites, stating that the shake process is independent of the reemission shell. These (1s3d) under bar shake satellites rapidly reach their saturation limit in contrast to Cu (1s2p) under bar and (1s1s) under bar shake satellites. Furthermore, the contribution of the KMN and the KNN radiative Auger satellites to the Cu Kbeta(1,3) and Cu Kbeta(2,5) emission spectra is obtained, respectively. The KNN radiative Auger satellite is shown to play an important role in the interpretation of valence fluorescence spectra.
