  "abstract": "Various measurements of the Coulomb breakup of 8B are analyzed within the dynamical eikonal approximation using a single description of 8B. We obtain a good agreement with experiment for different observables measured between 40 and 80 MeV per nucleon. A simple 7Be-p potential model description of 8B seems sufficient to describe all observables. In particular, the asymmetry in parallel-momentum distributions due to E1-E2 interferences is well reproduced without any scaling. The projectile-target nuclear interactions seem negligible if data are selected at forward angles. On the contrary, like in previous analyzes we observe a significant influence of higher-order effects. The accuracy of astrophysical S factors for the 7Be(p,gamma)8B reaction at stellar energies extracted from breakup measurements therefore seems difficult to evaluate.",
