摘要

我们测量了在35mev下12C(7Be,3He)16O转移反应的角分布，该反应导致16O的几个激发态。在该反应中首次测量了16O基态的角分布。确定了所有观测状态对应的渐近归一化系数（ANC）。利用本研究得到的16O基态、6.92 MeV（2+）和7.12 MeV（1−）亚阈态的ANC，在r -矩阵分析中确定了12C(α,γ)16O反应的天体物理E1和E2 s因子。

The ANC of 16O states from 7Be + 12C α-transfer reaction to study 12C(α,γ)16O

We measured the angular distributions for theC(Be,He)O transfer reaction at 35 MeV leading to several excited states ofO. The angular distribution of the ground state ofO was measured for the first time in this reaction. The corresponding Asymptotic Normalization Coefficients (ANC) of all the observed states were determined. The ANC of ground state, 6.92 MeV (2

^{+}

) and 7.12 MeV (1

^{-}

) subthreshold states ofO obtained from this work are utilized to determine the astrophysical
