One-neutron knockout reactions of 24-28Ne in a beryllium target have been studied in the Fragment Separator (FRS), at GSI. The results include inclusive one-neutron knockout cross-sections as well as longitudinal-momentum distributions of the knockout fragments. The ground-state structure of the neutron-rich neon isotopes was obtained from an analysis of the measured momentum distributions. The results indicate that the two heaviest isotopes, 27Ne and 28Ne, are dominated by a configuration in which a s1 / 2 neutron is coupled to an excited state of the 26Ne and 27Ne core, respectively. © 2010 Elsevier B.V.
