| contents | The electromagnetic dipole transitions in $^7$Be($p,γ$)$^8$B and $^7$Li($n,γ$)$^8$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 non-resonant 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 $^7$Be($p,γ$)$^8$B reaction, and the one at $222$ keV of $^7$Li($n,γ$)$^8$Li are also analyzed. The astrophysical $\mathcal{S}_{17}(0)$ factor of $^7$Be($p,γ$)$^8$B reaction is found to be $22.3$ eV\,b. |
