Scientific paper

It is pointed out that Epstein's (1977) model for deuterium production via high-energy spallation reactions produces high-energy neutrinos in sufficient quantity to stand out above those that are produced by cosmic-ray interactions in earth's atmosphere. That the Reines experiment detected neutrinos of atmospheric origin without detecting any cosmic component restricts deuterium production by spallation reactions to very high redshifts (z at least about 300). Improved neutrino experiments may be able to push these limits back to recombination.
