Asymptotic normalization coefficients for 8B 7Be+p from a study of 8Li7Li+n Academic Article uri icon


  • Asymptotic normalization coefficients (ANCs) for 8Li 7Li+n have been extracted from the neutron transfer reaction 13C(7Li,8Li) 12C at 63 MeV. These are related to the ANCs in 8B7Be+p using charge symmetry. We extract ANCs for 8B which are in very good agreement with those inferred from proton transfer and breakup experiments. We have also separated the contributions from the p 1/2 and p 3/2 components in the transfer. We find the astrophysical factor for the 7Be(p,)8B reaction to be S17(0) = 17.6 1.7 eVb. This is the first time that the rate of a direct capture reaction of astrophysical interest has been determined through a measurement of the ANCs in the mirror system.
