KLL Auger transitions in metallic Cu and Ni

The X-ray excited KLL Auger spectra of polycrystalline Cu and Ni films, measured with high energy resolution and presented here, show intensive satellite structures of intrinsic origin. A good agreement is between the determined relative KL23L23 energies or KL3L3 relative intensities and their experimental (Cu) and theoretical (free atoms) values obtained earlier. However, the deviation is significant for the absolute Auger transition energies and very large for the relative intensity of the Ni KL2L2(S-1(0)) Line or of the initial state shakeup satellites.
