摘要/描述

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 DE-E counter telescope. The reaction cross section was determined to be 58±8mb. The angular istribution data were analyzed with the distorted-wave Born approximation calculation. The astrophysical S17s0d 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
