ResumoThe cross section for Coulomb dissociation of $^{8}\mathrm{B}$---the $^{208}\mathrm{Pb}(^{8}\mathrm{B}^{7}\mathrm{Be}p)^{208}\mathrm{Pb}$ reaction---was measured using a $^{8}\mathrm{B}$ radioactive beam of 46.5 MeV/nucleon energy, and the cross section for the $^{7}\mathrm{Be}(p,\ensuremath{\gamma})^{8}\mathrm{B}$ capture reaction was deduced at low energies; ${E}_{\mathrm{c}.\mathrm{m}.}=0.6\ensuremath{-}1.7$ 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 $^{8}\mathrm{B}$ solar neutrino flux.
