研究了在铍中阻止25、35、45和55 MeV质子产生中子的情况。正向中子产额可近似为：产额= -0.032X10（16）·E+0.0027X10（16）·E2中子/Csr，中子能谱的特征是低能蒸发成分和高能成分，前者角依赖性小，后者在正向有峰值。正向产生的中子的平均能量约为入射质子能量的40%。
The production of neutrons by stopping 25-, 35-, 45-, and 55-MeV protons in beryllium has been studied. The yield of neutrons in the forward direction can be approximated by the relation: yield = -0.032X10(16).E+0.0027X10(16).E2 neutrons/C sr. The neutron spectra are characterized by a low-energy evaporation component which has small angular dependence and a high-energy component which is peaked in the forward direction. Neutrons produced in the forward direction have an average energy approximately 40% of the incident proton energy.
