The astrophysical factor for 7Be(p,\gamma)8B at zero energy, S17(0), isdetermined from an analysis of 208Pb(8B, p+7Be)208Pb at 52 MeV/nucleon by meansof the method of continuum-discretized coupled-channels (CDCC) taking accountof all nuclear and Coulomb breakup processes. The asymptotic normalizationcoefficient (ANC) method is used to extract S17(0) from the calculatedbreakup-cross-section. The main result of the present paper is S17(0)=20.9+2.0/-1.9 eV b. The error consists of 8.4% experimental systematic error andthe error due to the ambiguity in the s-wave p-7Be scattering length. Thisvalue of S17(0) differs from the one extracted with the first-orderperturbation theory including Coulomb breakup by dipole transitions: 18.9 +/-1.8 eV b. It turns out that the difference is due to the inclusion of thenuclear and Coulomb-quadrupole transitions and multi-step processes ofall-order in the present work. The p-7Be interaction potential used in the CDCCcalculation is also used in the ANC analysis of 7Be(p,\gamma)8B. The value ofS17(0)=21.7 +0.62/-0.55 eV b obtained is consistent with the previous oneobtained from a precise measurement of the p-capture reaction cross sectionextrapolated to zero incident energy, S17(0)=22.1 +/- 0.6 (expt) +/- 0.6 (theo)eV b, where (theo) stands for the error in the extrapolation. Thus, theagreement between the values of S17(0) obtained from direct 7Be(p,\gamma)8B andindirect 8B-breakup measurements is significantly improved.Comment: 13 pages, 9 figures, published in PR
