Abstract
This Letter reports a direct measurement of the 7Be solar neutrino signal rate performed with the Borexino low background liquid scintillator detector at the Laboratori Nazionali del Gran Sasso. This is the first real-time spectral measurement of sub-MeV solar neutrinos. The result for 0.862 MeV 7Be neutrinos is 47 ± 7stat ± 12sys counts/(day ṡ 100 ton), consistent with predictions of Standard Solar Models and neutrino oscillations with LMA-MSW parameters.
