Abstract
The electromagnetic dipole transitions in $^{7}\mathrm{Be}(p,\ensuremath{\gamma})^{8}\mathrm{B}$ and $^{7}\mathrm{Li}(n,\ensuremath{\gamma})^{8}\mathrm{Li}$ reactions at the keV-energy region were analyzed simultaneously within the Skyrme Hartree-Fock potential model. The Skyrme Hartree-Fock calculation is adopted as a microscopic approach to obtain consistently the single-particle bound and scattering states in the calculation of the radial overlap function within the potential model. All nonresonant and resonant electromagnetic dipole transitions are taken into account. The electric dipole transitions are successfully described with the slightest adjustment. The resonant magnetic dipole transitions at 633 keV and 2184 keV of the $^{7}\mathrm{Be}(p,\ensuremath{\gamma})^{8}\mathrm{B}$ reaction, and the one at 222 keV of $^{7}\mathrm{Li}(n,\ensuremath{\gamma})^{8}\mathrm{Li}$ are also analyzed. The astrophysical ${\mathcal{S}}_{17}(0)$ factor of the $^{7}\mathrm{Be}(p,\ensuremath{\gamma})^{8}\mathrm{B}$ reaction is found to be 22.3 eV b.
