摘要：

We calculate the flux of neutrinos generated by the propagation of ultra-high energy iron over cosmological distances and show that even if ultra-high energy cosmic rays are composed of heavy nuclei, a significant flux of high-energy neutrinos should be present throughout the universe. The resulting neutrino flux has a new peak at similar to10(14) eV generated by neutron decay and reproduces the double peak structure due to photopion production at higher energies (similar to 10(IS) eV). Depending on the maximum energy and cosmological evolution of extremely high energy cosmic accelerators the generated neutrino flux can be detected by future experiments. (C) 2004 Elsevier Ltd.
