Аннотация:We present spectra and mass composition of cosmic rays incoming to the Earth in the energy range (0.5-2) . 10(20) eV. As their sources we consider Seyfert galaxies located at distances less than or similar to 40 Mpc, following an acceleration model for such moderate-power objects. Mass composition of the particles at sources is assumed to be mixed. Generation spectra are described by a function E-gamma 0, where gamma(0) is an arbitrary parameter. It is shown that the assumptions adopted make it possible to describe experimental data provided by HiRes and Pierre Auger Observatory, using different values of gamma(0).
