Research Abstract

We have constructed large neutron hodoscope necessary for measuring radii of strongly-bound inner-shell neutrons in unstable nuclei. Experiment was proposed and approved by RIKEN RIBF-PAC. All the detector system necessary for (p, 2p)and (p, pn)reactions has been installed in the experimental area. Data for 6, 8He, 7, 8, 9, 11Li (p, 2p)reactions have been collected in June 2010.
