Breakup of B-8 and the S-17 astrophysical factor reexamined

Existing experimental data for the breakup of $^{8}\mathrm{B}$ at energies from 30 to $1000\phantom{\rule{0.3em}{0ex}}\text{MeV}∕\text{nucleon}$ on light through heavy targets are analyzed in detail in terms of an extended Glauber model. The predictions of the model are in excellent agreement with independent reaction data (reaction cross sections and parallel momentum distributions for corelike fragments). Final-state interactions have been included in the Coulomb dissociation component. We extract asymptotic normalization coefficients (ANC) from which the astrophysical factor ${S}_{17}(0)$ for the key reaction for solar neutrino production, $^{7}\mathrm{Be}(p,\ensuremath{\gamma})^{8}\mathrm{B}$, can be evaluated. Glauber model calculations using different effective interactions give consistent, though slightly different results. The differences give a measure of the precision one can expect from the method. The unweighted average of all ANCs extracted leads to ${S}_{17}(0)=18.7\ifmmode\pm\else\textpm\fi{}1.9\phantom{\rule{0.3em}{0ex}}\text{eV}\phantom{\rule{0.3em}{0ex}}\mathrm{b}$. The results of this new analysis are compared with the earlier one. They are consistent with the values from most direct measurements and other indirect methods.
