We show that neutrino-photon reactions above m(e) are dominated by the reaction vy → ve+e-. We calculate its cross-section and see that it is larger by several orders of magnitude than the cross-sections of other neutrino-photon processes, for energies above m(e). We also discuss potential astrophysical and cosmological consequences. (C) 2000 Published by Elsevier Science B.V.
