Measurement of Double Differential Neutron Yields from Thick Aluminum Target Irradiated by 9 MeV Deuteron

Double differential neutron yields from a thick aluminum target irradiated by 9 MeV deuterons were measured at the Kyushu University Tandem accelerator Laboratory (KUTL). An NE213 liquid organic scintillator (50.4 mm thick and 50.4 mm in diameter) was used as a neutron detector. Neutron yields from the target were measured at nine angles between 0° and 140°. The neutron energy spectra were obtained by means of an unfolding method using FORIST code with the response function of the NE213 scintillator calculated by SCINFUL-QMD code. The experimental result was compared with other measured data at 5 and 40 MeV and the calculation based on intra-nuclear cascade of Liège (INCL) model in PHITS code.
