Abstract

The cross section for Coulomb dissociation of B8-the Pb208(B8Be7p)Pb208 reaction-was measured using a B8 radioactive beam of 46.5 MeV/nucleon energy, and the cross section for the Be7(p,γ)B8 capture reaction was deduced at low energies; Ec. m.=0.6-1.7 MeV. The extracted astrophysical S17 factors were found to be consistent with the values measured by Vaughn et al. and Filippone et al. This result encourages further experimental studies extended to lower relative energies for a new determination of the S17 value relevant to the B8 solar neutrino flux.
