    "abstract": "We present S factor data obtained from the Coulomb dissociation of 83\nMeV/nucleon 8B, and analyze 7Be longitudinal momentum distributions measured at\n44 and 81 MeV/nucleon using a potential model, first-order perturbation theory,\nand dynamical solution of the time-dependent Schroedinger equation. Comparing\nour results with independent continuum-discretized coupled channels\ncalculations, we study the reaction model and beam energy dependence of the E2\ncontribution to the dissociation cross section. By fitting radiative capture\nand Coulomb breakup data taken below relative energies of 400 keV with\npotential models constrained by 7Li + n and 7Be + p elastic scattering data, we\nexamine the mutual consistency of recent S17 measurements and obtain a\nrecommended value for S17(0) of 18.6 +/- 0.4 (experimental) +/- 1.1\n(extrapolation) eV b (1 sigma). This result is in good agreement with recent\nexperimental determinations of the asymptotic normalization coefficient of the\nvalence proton wave function in 8B.",
