The composition of ultrahigh energy cosmic rays is yet unknown. The photo-disintegration of cosmic ray nuclei by star light leads to the production of secondary antineutrinos and gamma rays. We have calculated the antineutrino flux produced in this way from ultrahigh energy cosmic ray nuclei trapped close to the Galactic plane where the radiation field is intense. The IceCube detector has measured the neutrino/antineutrino flux in the TeV-PeV energy range. Our calculated secondary antineutrino flux in the energy range of 28-100 TeV is compared with the neutrino/antineutrino flux detected by the IceCube detector to constrain the flux of heavy nuclei of per nucleon energy 27-98 PeV.
