Abstract
Interaction cross sections ({sigma}{sub 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 {sigma}{sub I} for {sup 27-32}Ne in every case exceed the systematic mass-number dependence of {sigma}{sub I} for stable nuclei, which can be explained by considering the nuclear deformation. In particular the {sigma}{sub I} for {sup 29}Ne and {sup 31}Ne are significantly greater than those of their neighboring nuclides. These enhancements of {sigma}{sub I} for {sup 29}Ne and {sup 31}Ne cannot be explained by a single-particle model calculation under the assumption that the valence neutron of {sup 29}Ne ({sup 31}Ne) occupies the 0d{sub 3/2} (0f{sub 7/2}) orbital, as expected from the standard spherical shell ordering. The present data suggest an s dominant halo structure of {sup 29}Ne and s- or p-orbital halo in {sup 31}Ne.
