Possibility of 8B solar neutrino detection via 19F inverse beta-decay reactions

Abstract

A method to detect 8B solar neutrinos is proposed using the charge current reaction ν e 19F with a hexafluorobenzene scintillation detector. The main advantage of the detector is the possibility of identifying neutrino events by a delayed coincidence with the β + decay of 19Ne ( T 1 2 = 17 s ). Because of this the detector is potentially sensitive to neutrinos with an energy as low as 5 MeV. An additional advantage of the detector is the ability to select unambiguously the electron neutrino component of the burst from a stellar gravitational collapse.
