Abstract
A simple method for measuring the efficiency of BaF2 crystal to neutro ns of energy up to 11 MeV is here described. The method relies on the simultaneous detection of neutrons and gamma-rays from fission events of a Cf-252 source. The detection efficiency of a 5 cm thick BaF2 crys tal has been measured as a function of the neutron energy and threshol d on the light output, and the experimental values have been compared with the results of a GEANT-based Monte Carlo calculation.
