针对被称为聚变反应堆先进增殖材料的LiAlO2、li2tio3和Li2ZrO3三种材料，在日本原子能研究所（JAERI）的聚变中子源（FNS）上进行了D-T中子基准实验，验证了JENDL-3.2、JENDL聚变文件、ENDF/B-VI、FENDL/E-1.0和FENDL/E-2.0五个核数据文件。结果表明，利用lialo2和Li2TiO3对中子谱的预测，所有核数据文件都是相当可靠的。但是，建议对5个核数据文件中氧、锂和铝的非弹性散射中子谱进行重新检查。对于锆，指出5个核数据文件的zr （n, 2n）截面可能被高估。
For the three materials LiAlO2, Li2TiO3and Li2ZrO3, known as advanced breeder materials for a fusion reactor, D–T neutron benchmark experiments have been conducted at fusion neutronics source (FNS) of Japan Atomic Energy Research Institute (JAERI), Japan, to validate five nuclear data files, i.e. JENDL-3.2, JENDL fusion file, ENDF/B-VI, FENDL/E-1.0 and FENDL/E-2.0. From the result, all the nuclear data files were confirmed to be fairly reliable with respect to the prediction of neutron spectrum in the use of LiAlO2and Li2TiO3. However, it was recommended that the inelastic scattering neutron spectra of oxygen, lithium and aluminium in the five nuclear data files had to be re-examined. As for zirconium, it was pointed out that thenatZr(n, 2n) cross section could be overestimated for the five nuclear data files.
