摘要：

A new semi-empirical 7-parametric formula for the calculation of (n, alpha) reaction cross sections at an energy of 14.5 MeV is suggested. To derive it the analytical expressions describing the alpha-particle emission spectrum within the frame of the pre-equilibrium exciton and the evaporation models were used. The systematics obtained ensures better agreement with experimental data than empirical systematics suggested earlier by other authors.
