Low-energy Li-7(n, gamma) Li-8 and Be-7(p, gamma)B- 8 radiative capture reactions within the Skyrme Hartree-Fock approach

Abstract

The electromagnetic dipole transitions in 7Be(p, ?? ) 8B and 7Li(n, ?? ) 8Li 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 7Be(p, ?? ) 8B reaction, and the one at 222 keV of 7Li(n, ?? ) 8Li are also analyzed. The astrophysical S17(0) factor of the 7Be(p, ?? ) 8B reaction is found to be 22.3 eV b.
