The KLL Auger electron spectrum of Cu-65 following the EC decay of Zn-65 has been analyzed at the instrumental resolution of 4.5 and 7 eV using a combined electrostatic spectrometer. Energies and relative intensities of the all nine spectrum components were determined and compared with data obtained from X-ray induced spectra for metallic copper and with results of theories as well. Our value of 7041.8(1.3) eV measured for the absolute energy of the dominant KL2L3(D-1(2)) spectrum line was found to be higher by 4 eV than those ones obtained in experiments with the use of X-ray photon excitation and by 11 eV (8 sigma) than a prediction of the semi-empirical calculations by Larkins. This discrepancy indicates an influence of the "atomic structure effect" on absolute energies of the KLL Auger transitions in Cu-65.
