Abstract

The photoexcited Kα satellite spectra for Fe (Z = 26), Ni (Z = 28) and Zn (Z = 30) were measured with an x-ray crystal spectrometer using synchrotron radiation. The intensity variation of the KαL1 satellite lines was obtained as a function of the excitation photon energy, from threshold to saturation. While the excitation energy increases, the continuous intensity rise from threshold to saturation could be explained by the shake-off process for inner-shell electrons of the medium-Z atoms. Applying the analytic Thomas model to the experimental data, the evolution of the KαL1/Kα1,2 intensity ratio, the threshold energy and the radius of the shake shell were determined.
