摘要：
We reexamine the interaction of ultrahigh energy nuclei with the microwave background radiation. We find that the giant dipole resonance leaves a new signature in the differential energy spectrum of iron sources located around 3 Mpc: A depression before a bump which is followed by the expected cutoff.
