Abstract

Interaction cross sections (σ _I) for Ne isotopes from the stability line to the vicinity of the neutron drip line have been measured at around 240 MeV/nucleon using BigRIPS at RIBF, RIKEN. The σ _I for ^27-32Ne in every case exceed the systematic mass-number dependence of σ _I for stable nuclei, which can be explained by considering the nuclear deformation. In particular the σ _I for ²⁹Ne and ³¹Ne are significantly greater than those of their neighboring nuclides. These enhancements of σ _I for ²⁹Ne and ³¹Ne cannot be explained by a single-particle model calculation under the assumption that the valence neutron of ²⁹Ne ( ³¹Ne) occupies the 0d _3/2 (0f _7/2) orbital, as expected from the standard spherical shell ordering. The present data suggest an s dominant halo structure of ²⁹Ne and s- or p-orbital halo in ³¹Ne.
