建立了一个数学模型和计算机程序，用于计算入射-氚能范围为0.5-20.0 MeV范围内Be(d，n)反应的能谱、角分布和积分产额。程序中采用了Talys程序计算的双差分截面和SRIM-2010程序推导的截止力。给出了典型的计算结果，并与以前的实验数据进行了比较，以评价计算模型和厚Be靶的Be($d，$n)反应特性。此外，所发展的理论和计算方法还可以为双差截面和截止力的计算数据提供合理的评价。该模型和程序能在0.5~20.0 MeV能量范围内预测以厚铍靶为中子源的Be(d，n)反应的上述特征参数。
A mathematical model and a computer program are developed to calculate the neutron energy spectrum, angular distribution, and integrated yield of the ${}^{9}$Be($d$,$n$) reaction on a thick beryllium target as an accelerator-based neutron source in the incident-deuteron-energy range from 0.5 to 20.0 MeV. The double-differential cross section computed by the talys code and the stopping power derived from the SRIM-2010 code are adopted in the program. Typical computational results are presented, and are compared with the previous experimental data to evaluate the computing model as well as the characteristics of the ${}^{9}$Be($d$,$n$) reaction with a thick Be target. Moreover, the developed theory and calculation methods can also provide a reasonable evaluation for calculating data of double-differential cross sections and stopping power. This model and the program can predict the above characteristics parameters of the ${}^{9}$Be($d$,$n$) reaction for a thick beryllium target as a neutron source in the incident-deuteron-energy range from 0.5 to 20.0 MeV.
