摘要：

We have calculated the E1 and E2 contributions to the low-energy B-8 + PB-208 --> p + Be-7 + Pb-208 Coulomb dissociation cross sections using the kinematics of a recent experiment at RIKEN. Using a potential model description of the Be-7(p, gamma)B-8 reaction, we find that the E2 contributions cannot a priori be ignored in the analysis of the data. Its inclusion reduces the extracted Be-7(p,gamma)B-8 S-factor at solar energies by about 25%.
