The cross-section calculation systematics for nuclear reactions have great importance in describing the particle-induced excitation of nuclei. In this study, for 14–15 MeV of incident neutron energy, it has been suggested new empirical formulae to describe the (n, 2p) reactions cross sections. The new empirical formulae have been obtained for 29≤A≤159, 29≤A≤103 and 133≤A≤159 mass ranges which are dependent on s=(N–Z)/A asymmetry parameter. The asymmetry parameters have been obtained by modifying the original Levkovski formula. Then, EXFOR data has been studied by applying the least square fitting method and (n, 2p) reactions systematics has been revealed. The statistical dependence (R²) of these data was examined in the 29≤A≤159 total mass range. The calculated results from the obtained formulae have been compared with the literature data. The predictions of our formulae are in good agreement with the EXFOR data for 29≤A≤159 and 29≤A≤103 mass range.

核反应的横截面计算系统在描述粒子诱发的核激发方面具有重要意义。在这项研究中，对于入射中子能量为14-15 MeV的情况，已经提出了新的经验公式来描述（n，2p）反应截面。对于29≤A≤159、29≤A≤103和133≤A≤159的质量范围，已获得新的经验公式，这些公式取决于s =（N–Z）/ A不对称参数。不对称参数是通过修改原始的列夫科夫斯基公式获得的。然后，通过应用最小二乘拟合法研究了EXFOR数据，并揭示了（n，2p）反应系统。统计依赖性（R ²）在29≤A≤159的总质量范围内检查了这些数据。从获得的公式计算的结果已与文献数据进行了比较。我们的公式的预测与质量范围为29≤A≤159和29≤A≤103的EXFOR数据高度吻合。
