Abstract

Interaction cross sections of mass number A=17 isobar (₇¹⁷N₁₀, ₉¹⁷F₈, and ₁₀¹⁷Ne₇) have been measured at around 700 MeV/nucleon. Effective root-mean-square (RMS) radii of the nucleon distribution of these nuclei have been deduced using Glauber-model calculation. A strong isospin dependence of the radii has been observed in the A=17 isobar, which shows an increase of the radii on the proton rich side from ¹⁷F to ¹⁷Ne. The radius of ¹⁷Ne is also found to be larger than that of its mirror nucleus ¹⁷N. The increase of the radius in ¹⁷Ne suggests its anomalous structure. One of the possibilities is that an inversion of the s and d orbitals occurs in this nucleus. The role of the centrifugal barrier in the formation of a halo is also discussed.
