Description

Neutron response functions of 12.7 cm diameter by 12.7 cm long BC501A organic liquid scintillator have been measured for energy range up to 135 MeV continuously with the TOF method. The measured response functions were compared with Monte Carlo calculations using some codes which are widely used. The comparison showed good agreement below 20 MeV, but some discrepancy above 20 MeV, owing to the inaccurate cross sections of carbon reactions and light yields of produced charged particles. Finally, the new response matrix which covered from 0 to 120 MeV based on the measured data was constructed by the help of calculation data. (orig.)
