Abstract

The cross section for Coulomb dissociation of ${}^{8}B$ —the ${}^{208}{Pb} ({}^{8}B {}^{7}{Be} p) {}^{208}{Pb}$ reaction—was measured using a ${}^{8}B$ radioactive beam of 46.5 MeV/nucleon energy, and the cross section for the ${}^{7}{Be} (p, γ) {}^{8}B$ capture reaction was deduced at low energies; $E_{c . m .} = 0.6 - 1.7$ MeV. The extracted astrophysical $S_{17}$ 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 $S_{17}$ value relevant to the ${}^{8}B$ solar neutrino flux.
