The 10B(7Be,8B)9Be reaction has been studied with an 84 MeV 7Be radioactive beam. The measured cross section determines the asymptotic normalization coefficients for the virtual transitions 7Be+p↔8B. These coefficients specify the amplitude of the tail of the 8B wave function in the two-body channel 7Be+p, and may be used to calculate the S factor for the direct capture reaction 7Be(p,γ)8B at solar energies, S17(0). We find that S17(0) = 17.8±2.8eVb.
