Megjegyzések:	Ni and Cu KLL Auger spectra excited by X-rays from polycrystalline metal foils were measured with goodenergy resolution and intensity earlier. Auger spectra of 3d transition metals contain satellite peaks dueto the atomic excitation processes. Because of the complexity of the measured spectral shape a completeexplanation of the spectra was not given in the previous works. A new analysis of the measured spectra ispresented here, with improved description of effects of inelastic electron scattering of the electrons in thesolid sample and using complex peak shapes to model the satellite structure that follows each diagramline. The energy loss part of measured spectra due to the bulk plasmon excitations, surface plasmon exci-tations and intrinsic loss processes was removed using the Partial Intensity Analysis method based onenergy loss distributions obtained from experimental reflection electron energy loss spectra of the sameCu and Ni metal foils.Relative Auger-transition energies derived from measured spectra of copper are in good agreementwith previous experimental works and the results of cluster molecular orbital multielectron (DV-ME) cal-culations. The intensity ratio I(3P2/3P0) shows better agreement with the result of relativistic calculationsthan in previous works. In the case of nickel the relative Auger-transition energies are in good agreementwith the previous results. According to the new evaluation four satellite peaks were identified on the lowenergy side of each diagram line in the Auger spectra of Ni.
