Angular Distribution for 7Be(d, n)8B Reaction at Ec.m. = 8.3 MeV and the Astrophysical S17(0) Factor for 7Be(p, γ)8B Reaction
Abstract
The differential cross section for 7Be(d, n)8B reaction at Ec.m. = 8.3 MeV has been measured by using a 7Be radioactive beam. The reaction cross section was determined to be 28 ± 3 mb. The astrophysical S17(0) factor for the 7Be(p,γ)8B reaction was derived to be 24 ± 5 eV b through the asymptotic normalization constant of 8B extracted from the experimental data. This result is found to be consistent with a previous value obtained from the same reaction at Ec.m. = 5.8 MeV, implying the energy independence of this indirect method within the uncertainty.
