Abstract
Various measurements of the Coulomb breakup of are analyzed within the dynamical eikonal approximation using a single description of . We obtain a good agreement with experiment for different observables measured between 40 and 80 MeV/nucleon. A simple - potential model description of seems sufficient to describe all observables. In particular, the asymmetry in parallel-momentum distributions due to 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 analyses we observe a significant influence of higher-order effects. The accuracy of astrophysical factors for the () reaction at stellar energies extracted from breakup measurements therefore seems difficult to evaluate.
