value: below 20 mev.
type: OTHER
Source sentences:
text: Solar neutrinos have energies below 20 MeV.
text: For example, most solar neutrinos have energies on the order of 0.100 MeV–1 MeV, so the fraction of neutrinos with "wrong" helicity among them cannot exceed 10−10.
text: Solar neutrinos have energies smaller than the mass of muons and tau leptons, so only electron neutrinos can participate in this reaction.
