Abstract
The x-ray emission of Cu metal has been measured using monochromatic synchrotron radiation. The self-absorption effect in the spectra is shown to be very small in our experimental geometry. From the quantitative analysis of spectra recorded at different excitation energies, the emission intensity ratio and the partial Auger width are extracted. High-energy satellite features on the emission line are separated by a subtraction procedure. The satellite intensity is found to be slowly increasing for excitation energies between the and core-level thresholds due to shake-up and shake-off transitions. As the excitation energy passes the threshold, a step of rapidly increasing satellite intensity of the emission is found due to additional Coster-Kronig processes.
