Phys. Rev. D 50, 1892–1900 (1994)Influence of the universal microwave background radiation on the extragalactic cosmic-ray spectrumReceived 7 March 1994; published in the issue dated 1 August 1994 Features of the spectrum of the most energetic cosmic-ray protons produced by their passage through the 2.7 K universal background radiation are investigated by Monte Carlo techniques. We discuss the influence of various factors on the spectrum of protons observed at Earth with energies above 3×1019 eV. These factors include the shape of the initial cosmic-ray spectrum, the spatial distribution of sources, and the energy-dependent diffusion and escape of particles from a confinement region. © 1994 The American Physical Society URL:
