Abstract

The differential cross section for the 7Be(d,n)8B reaction at Ec.m.=5.8 MeV has been measured using the 7Be beam generated by the radioactive nuclear beam facility at China Institute of Atomic Energy. The 8B ions were detected in full geometry with a two-dimensional position sensitive ΔE- E counter telescope. The reaction cross section was determined to be 58±8 mb. The angular distribution data were analyzed with the distorted-wave Born approximation calculation. The astrophysical S17(0) factor for the 7Be(p,γ)8B reaction was derived to be 27.4±4.4 eV b through the asymptotic normalization constant extracted from the experimental data.
