Measurements of interaction cross sections towards neutron-rich Ne isotopes at RIBF

摘要

Interaction cross sections (σ_I) for Ne isotopes from the stability line to the vicinity of neutron-drip line have been measured using the RIBF facility at RIKEN. Measurements have been performed for ~(2032)Ne on C target at energies around 240 MeVucleon. A large enhancement of σ_I beyond the systematics of stable nuclei have been observed for neutron-rich Ne isotopes. The possible halo structures with lower orbital angular momentum for ~(29,31)Ne are discussed by the preliminary analysis.
