Abstract

The Coulomb-dissociation cross section for the process 8B → 7Be + p in the field of 208Pb was measured at E(8B) = 46.5 A MeV. The 7Be(p,γ)8B cross section relevant to the high-energy 8B solar-neutrino production was extracted at EC.M. = 0.6-1.7 MeV. Two theoretical models on the structure of 8B were used to evaluate possible corrections due to M1 and E2 admixtures to the dominant El cross sections. Their overall effect is shown to be small regardless of the choice of the models. The present result is consistent with the results of the direct measurements of Filippone et al. and Vaughn et al. within errors. This result suggests further studies with the Coulomb-dissociation method to extract astrophysical S17 factor at ∼ 20 keV relevant to the high-energy solar-neutrino flux.
