The Need to Measure Low Energy Anti-Neutrinos (E < 0.782MeV) from the   Sun
  Measurements are needed of low energy, anti-neutrinos generated by possible neutron decay at the core of the Sun. The measurement will test the validity of a proposal that solar luminosity, neutrinos, and the solar wind are products of a chain of reactions triggered by neutron emission from the solar core. Inverse beta-decay of 87-day S-35, induced by capture of low-energy anti-neutrinos on Cl-35, is a likely candidate for this measurement.
