摘要

我们报告了低能下 19F(p,α0,π)16O反应的新横截面数据，特别是在 1.1-1.3 MeV 区域和 1.6-1.7 MeV 能量区域，前者的 απ 通道数据很少见，后者则解决了 α0 通道现有数据集之间长期存在的差异。新数据被纳入了一个全面的 R 矩阵拟合，并讨论了关于 14-15 MeV 激发能区 20Ne 态团簇性质的一些建议。

New measurements of the 19F(p, α0,π)16O reaction cross sections close to the Coulomb barrier

We report new cross section data for the ¹⁹F(p,

α_{0, π}

)¹⁶O reactions at low energies, especially in the 1.1-1.3 MeV region, where few data for the

α_{π}

channel are reported, and in the 1.6-1.7 MeV energy region, to solve a long-standing discrepancy between existing data sets for the

α_{0}

channel. The new data were included in a comprehensive R-matrix fit, and some suggestions on the cluster nature of ²⁰Ne states in the 14-15 MeV excitation energy region were discussed.
