摘要: 本文研究中等和重质量核14MeV中子(n,t)反应截面的系统学特征,在考虑奇偶效应的基础上给出了系统学经验公式,计算结果和实验值符合较好,还讨论了Q值效应及可能的反应机制。 The systemaic characters of (n,t) reaction cross sections have been studied for mediumand heavy mass nuclei at 14 MeV. A set of the empirical formulas have been given on the bases of theodd-even effects. The (n,t) reaction cross sections of some nuclei have been calculated, and a goodagreement with the experimental data have been obtained. The Q-value effect and possible reactionmechanism are also discussed.
