Abstract

The Coulomb dissociation was proven to be a valuable method to provide a rather precise value for the low-energy 7Be(p,γ) cross section. By setting tight constraints to the scattering angle θ8 and analyzing p-7Be angular correlations, a significant contribution from E2 multipolarity can be excluded. Thus, small modifications of the Woods-Saxon potential parameters allow one to reproduce the data in first-order perturbation theory with remarkable accuracy up to about Erel=1.5 MeV.
