Is there a 4.5 PeV neutron line in the cosmic ray spectrum?

Recently we presented a model to fit the cosmic ray spectrum using the hypothesis that the electron neutrino is a tachyon. The model predicted the existence of a neutron flux in the cosmic rays in a narrow region centered on $E=4.5\mathrm{}\pm 2.2\mathrm{PeV}.$ The published literature on Cygnus X-3 reveals just such a 6σ spike of neutral particles centered on $E=4.5\mathrm{}\mathrm{PeV}.$ A second prediction of the model concerning integrated neutron fluxes at several energies also is consistent with published data. A specific further test of the model is proposed.
