用透射法在9个Be、12个C和17个Al靶上测量了质子滴线核17ne在64和42 MeV/核子下的反应截面（σ R）。从包含高能数据的σ R的能量依赖性出发，通过修正的glauber型计算推导出了17 Ne的密度分布。结果表明，17ne在密度上有一条长尾，符合两价质子的（2s 1/2） 2优势构型。
Reaction cross sections (σ R ) for the proton drip-line nucleus 17 Ne have been measured on 9 Be, 12 C, and 17 Al targets at 64 and 42 MeV/nucleon by the transmission method. From the energy dependence of the σ R including the high energy data, the density distribution of 17 Ne was deduced through a modified Glauber-type calculation. It is indicated that 17 Ne has a long tail in the density, consistent with a (2s 1/2 ) 2 -dominant configuration of two valence protons.
