Аннотация
The ${}^{14}\mathrm{N}{(}^{7}\mathrm{Be}{,}^{8}\mathrm{B}{)}^{13}\mathrm{C}$ reaction was studied using an 85 MeV ${}^{7}\mathrm{Be}$ radioactive beam. The asymptotic normalization coefficients for the virtual transitions ${}^{7}\mathrm{Be}+p{\ensuremath{\leftrightarrow}}^{8}\mathrm{B}$ were determined from the measured cross section. These coefficients specify the amplitude of the tail of the ${}^{8}\mathrm{B}$ overlap function in the ${}^{7}\mathrm{Be}+p$ channel, and were used to calculate the astrophysical S factor for the direct capture reaction ${}^{7}\mathrm{Be}(p,\ensuremath{\gamma}{)}^{8}\mathrm{B}$ at solar energies ${S}_{17}(0).$ We find that ${S}_{17}(0)=16.6\ifmmode\pm\else\textpm\fi{}1.9$ eV b.
