[en] Vibration spectra of carbon atoms in the α-iron irradiated by high energy electrons are studied by the method of internal friction. Samples have been irradiated by electrons with energy 4 MeV on linear accelerator up to fluences 10¹⁶-5·10¹⁷ sm^-2 at temperature not more 80 deg C. Beam current density is 1 μA/sm². Calculation of temperature dependences of internal friction were carried out by points under stabilized temperature before and after irradiation. It is shown, that form of distribution function of carbon atoms has been dissolved in α-iron by frequency of vibration changes in dependence from electron irradiation dose. The dose dependence of maximum shift of distribution function is nearly to linear one
