（n，t）反应截面的系统学计算

Calculation of the systematics for the (n,t) reaction cross sections

研究了中等和重质量核的１４ＭｅＶ（ｎ，ｔ）反应截面的系统学特性．在考虑奇偶效应的基础上给出了反应截面的系统学公式和经验参数，利用这套参数计算了一些核素的反应截面，结果与测量值符合较好．并讨论了可能的反应机制和Ｑ值效应．

The systematic characters of the (n,t) reaction cross sections have been studied for medium and heavy mass nucleus at 14 MeV. A set of the empirical formula andparameters hae been extracted on the bases of considering odd-even effects. The (n, t)reaction cross sections of some nuclei have been calculated by means of given parameters,and a good agreement with measured data has been obtained. In addion, possible reaction mechanism and Q-value effects are also discussed.
