Contribution of the [1s3d] shake process to Kα1,2 spectra in 3d elements

The Kα1,2 emission lines in 3d transition elements were investigated using a high-resolution anti-parallel crystal spectrometer. A double Lorentzian model of the Kα X-ray emission spectra in these elements has been proved to be able to fit the experimental curve of the diffracted intensity like the case on Cu. Their energy positions, full-width at half-maximum (FWHM), and intensity ratio were obtained by Lorentzian fitting method for these diagram lines. Moreover, the contribution of the 3d spectator hole is experimentally and theoretically confirmed in the Zn Kα1,2 spectra using GRASP2 code for a convenience of the calculation.
