摘要：

An exclusive measurement of the Coulomb breakup of B-8 into Be-7 + p at 254A MeV allowed the study of the angular correlations of the breakup particles. These correlations demonstrate clearly that E1 multipolarity dominates and that E2 multipolarity can be neglected. By using a simple single-particle model for B-8 and treating the breakup in first-order perturbation theory, we extract a zero-energy S factor of S-17(0)=18.6 +/- 1.2 +/- 1.0 eV b, where the first error is experimental and the second one reflects the theoretical uncertainty in the extrapolation.
