为了满足能量在几百MeV以上的入射粒子场的活化-嬗变模拟的需要，FISPACT-II代码已被扩展为将TENDL标准ENDF-6核数据与扩展的核数据形式拼接在一起。JENDL-2007/HE和HEAD-2009库针对FISPACT-II进行了处理，并用于演示新代码版本的功能。对实验产额数据和最新的核内级联模型结果的库和比较的测试表明，有必要改进核数据库高达1 GeV以上。对铅靶的模拟表明，重要的放射性核素，如148 Gd，可以变化超过一个数量级，其中更先进的模型在实验不确定性范围内找到一致性。
To address the needs of activation-transmutation simulation in incident-particle fields with energies above a few hundred MeV, the FISPACT-II code has been extended to splice TENDL standard ENDF-6 nuclear data with extended nuclear data forms. The JENDL-2007/HE and HEAD-2009 libraries were processed for FISPACT-II and used to demonstrate the capabilities of the new code version. Tests of the libraries and comparisons against both experimental yield data and the most recent intra-nuclear cascade model results demonstrate that there is need for improved nuclear data libraries up to and above 1 GeV. Simulations on lead targets show that important radionuclides, such as 148Gd, can vary by more than an order of magnitude where more advanced models find agreement within the experimental uncertainties.
