✦ Synopsis

Neutrinos arising from 8 B β decay dominate the solar neutrino spectrum above 5 MeV, and primarily consist of neutrinos from the 8 B(2 + ) → 8 Be(2 + ) transition. Two other processes, 3 He+p and 8 B(2 + ) → 8 Be(0 + ) ground state second-forbidden decay, may also contribute to the solar neutrino flux in this energy region. Knowledge of the relative strengths of these three processes is important for accurate solar neutrino spectral shape measurements. We are attempting to measure the branching ratio of the 8 B(2 + ) → 8 Be(0 + ) ground state transition using an 8 B radioactive beam. Nuclear Physics A 746 (2004) 463c-466c
