“…A schematic view of the detection setup is given in figure 1. The experiment was described in detail in a recent article concerning the quasi-elastic scattering of 6 He [11], and only a brief outline relevant to the knockout reaction is given here [20]. The experiment was carried out at the RIKEN-RIPS beam line [21].…”

A knockout reaction experiment was carried out using a 6 He beam at 82.3 MeV/u impinged on carbon and hydrogen targets. The recoil protons were detected in coincidence with the forward moving charged fragments and neutrons. It is demonstrated that through the correlation between the recoil protons and forward moving charged fragments, the core fragment knockout and valence nucleon knockout reaction mechanisms can be discriminated at energies around 100 MeV/u. The 5 He ground-state resonance was reconstructed based on the selection of the valence nucleon knockout mechanism. The resonance parameters were obtained for both carbon and hydrogen targets, which are consistent with those previously reported in the literature. The importance of selecting appropriate reaction mechanisms is discussed based on reconstructions using events with larger transverse momentum transfer.

An experiment for knockout reaction induced by 8 He beam at 82.5 MeV/nucleon on CH2 and C targets was carried out. The 6 He and 4 He core fragments at forward angles and the recoiled protons at large angles were detected coincidently. From this exclusive measurement the valence nucleon knockout mechanism and the core knockout mechanism are separated, which can be applied to the exclusive spectroscopic study on the structure of exotic nuclei.

“…The correlation between the valence neutrons has been one of the most important problems studied intensively in the past years [1,5,6] . Experimentally breakup or knockout reactions have been widely used to investigate this kind of exotic structure and neutron correlation [7] . A neutron detector array [8∼10] with good detection efficiency and resolution is mandatory in these studies [11] .…”

“…Recently an experiment was carried out at RIKEN in Japan which applied the neutron walls in the forward direction as described in Ref. [7]. In order to extract correct information from the neutron detection, it is necessary to perform the detailed simulation to determine the various performance of the detector array and to decide the CT rejection algorithm to be used in the experimental data analysis.…”

Experimental data analysis and simulation calculations were performed in order to evaluate the cross-talk rejection performance of a typical neutron detection array. For very closely packed scintillation bars, the CT rejection may rely on the position relation between the two signals. The criteria | x| 15 cm and | y | 12 cm are currently proposed for a rejection rate higher than 90%. For signals coming from distanced bars, the energy conservation relationship can be applied to reject the CT events with a similar performance. In both cases the results of simulation agree very well with the experimental data, assuring their applicability to other detection systems and physics problems.
