Abstract
The parameterized theoretical formulae of excitation functions for (n, 2n) and (n, γ) reactions have been established, and for (n,tot), (n,non), (n,3n), (n,p), (n,d), (n,t), (n,3 He) and (n,α) have been recommended. According to these formulae, the SEF code have been developed for systematics calculation of these reactions. The calculated results with the systematics of the corresponding reactions of the discretional nucleus can be provided by the SEF code in the applied range quickly. At the same time, the comparison of calculated results with experimental and evaluated data can be given graphically.

Summary
The cross sections of neutron-induced reactions are important for nuclear science and technology. The evaluation of nuclear reaction cross sections are based on experimental measurement, theoretical calculation and systematics. The available measured data are scarce and scattered for some nuclei, reactions or energy regions. Based on the nuclear models, some codes [1, 2] have been developed and used to calculate the cross sections. The systematics is convenient and reliable for prediction of the neutron-induced reaction cross sections, compared to model theory calculations when experimental data are scarce. The parameterized theoretical formulae for (n, tot) ,(n, non), (n, 2n), (n, 3n), (n, γ), (n, p), (n, d), (n, t), (n,3 He) and (n, α) have been established or recommended, and the SEF code has been developed for systematics calculation
