摘要

The neutron yield for beryllium, vanadium and tantalum irradiated with 22, 27, 33 and 42MeV protons is indirectly determined by Prompt Gamma Neutron Activation Analysis (PGNAA). The neutron-to-gamma conversion rate is measured with an AmBe calibration neutron source. Corrections by escaped neutrons are applied via MCNP simulations of the experiment using the ENDF/B-VII.1 database. The experimental results are in good agreement with the neutron yield obtained from simulations deviating by 0.4% to 13%.
