Abstract

¹⁷Ne is one of the candidates for proton halo nuclei. To study the halo structure of ¹⁷Ne, we measured the reaction cross-sections ( σ^{} _R) and deduced the density distribution of ¹⁷Ne through the energy dependence of σ^{} _R. From the deduced density, it is found that ¹⁷Ne has a long density tail which is consistent with the picture of two valence protons of ¹⁷Ne occupying the 2s _1/2 orbital.
