چکیده انگلیسی
Interaction cross sections (ÏI) 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 ÏI for 27-32Ne in every case exceed the systematic mass-number dependence of ÏI for stable nuclei, which can be explained by considering the nuclear deformation. In particular the ÏI for 29Ne and 31Ne are significantly greater than those of their neighboring nuclides. These enhancements of ÏI 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 0d3/2 (0f7/2) 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.
