The Coulomb dissociation of 8B into 7Be and a proton was measured at E(8B) = 254 MeV/u. The astrophysical S17-factors for the 7Be(p,γ)8B reaction were extracted at Ecm = 0.25 - 2.78 MeV yielding the zero-energy S17-factor relevant to the solar neutrino problem to be S17(0) = 20.6 ± 1.2 ± 1.0 eV-b. Our results agree with the direct measurement results of Vaughn et al., Filippone et al., and Hammache et al. as well as the Coulomb dissociation results of Motobayashi et al. and Kikuchi et al. at E(8B) ≈ 50 MeV/u.
