N2 - 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.
