Abstract

The 14N(7Be,8B)13C reaction was studied using an 85 MeV 7Be radioactive beam. The asymptotic normalization coefficients for the virtual transitions 7Be+p8B were determined from the measured cross section. These coefficients specify the amplitude of the tail of the 8B overlap function in the 7Be+p channel, and were used to calculate the astrophysical S factor for the direct capture reaction 7Be(p,γ)8B at solar energies S17(0). We find that S17(0)=16.6±1.9 eV b.
