An experimental study of the fine structure of the electron excited Cu Kα 1,2 doublet in the energy range 20‐40 ke V is presented. The spectra are different from earlier published ones in the sense that both the intensity and the resolution are high. A convex‐crystal setting of the spectrometer is discussed. It is pointed out that when using a point source in association with a convex crystal the broadening due to the curvature of the planes vanishes. The high intensity enables one to unambigiously introduce two Lorentzians. The characteristic profile and location of the difference between the experimental data points and the fits show that the asymmetry of the Cu Ka 1 and Kα 2 lines most probably is due to the radiative Auger mechanism K‐LM.
