The neutron yield for beryllium, vanadium and tantalum irradiated with 22, 27, 33 and 42 MeV 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%.

通过快速伽玛中子活化分析确定质子（22-42 MeV）照射的Be，V和Ta目标的中子收率

22、27、33和42 MeV质子辐照的铍，钒和钽的中子收率由快速伽马中子活化分析法（PGNAA）间接确定。用AmBe校准中子源测量中子至伽马转换率。使用ENDF / B-VII.1数据库通过实验的MCNP模拟对逃逸中子进行校正。实验结果与从模拟获得的中子产率偏离0.4％至13％很好。
