为了提高D-T热核聚变中子学计算的精度，对79种同位素和13种天然元素（从H到Bi）的次级中子双微分截面（DDX）进行了计算。本项目采用JENDL通用文件JENDL-3.1的最新版本，结合基于光学模型、DWBA、预平衡和多步统计模型的新计算，生成了基于各种系统学的中等质量核DDX数据。对于不能应用上述方法的轻核，采用了不同的方法。此外，还给出了~ 2 H、~ 9 Be和重于或等于F的元素的带电粒子（p、d、t、~ 3 He和α粒子）发射的DDX值。目前的结果给出了一个整体的中子和带电粒子发射通道的DDX测量数据的良好描述。数据以ENDF-6格式编制，并于1999年作为JENDL家族的专用文件发布，即JENDL Fusion File 99。
The double-differential cross sections (DDXs) of secondary neutrons have been evaluated for 79 isotopes and 13 natural elements ranging from H to Bi to improve the accuracy of predictions for the neutronics calculations in the D-T thermonuclear fusion applications. The data given in JENDL-3.1, which was the newest version of JENDL general purpose file when this project was initiated, was combined with new calculations based on the optical model, DWBA, pre-equilibrium and multi-step statistical models, and the DDX data were generated based on various kinds of systematics for medium-mass nuclei. Different methods were employed for light nuclei to which the above method could not be applied. In addition, the DDXs for emission of charged particles (p, d, t, 3He and α-particle) were given for 2H, 9Be and elements heavier or equal to F. The present results give an overall good description of the measured DDX data of both the neutron and charged particles emission channels. The data were compiled in ENDF-6 format, and released in 1999 as a special purpose file of JENDL family, namely, JENDL Fusion File 99.
