One of the most widely used neutron detectors for fast neutron is the organic liquid scintillator NE213 (or BC501A). The physical characteristic of the NE213 scintillator, such as detection efficiencies, has been studied and is well known in detail for neutrons below 20 MeV nowadays[1]. It is essential to study the efficiency of NE213 detector at high energy.
