Semi-empirical formula for calculating the average (n, α) reaction cross-section was derived by using the EXFOR experimental data at 14-15 MeV neutron energies for 133 target nuclei in the mass number range 9≤A≤209. In this new systematic, the non-elastic cross-section portion has been modified by [Formula: see text] , while the asymmetry parameter-dependent term has been maintained. Using EMPIRE 3.2.3 and TALYS 1.95, the (n, α) cross sections for selected nuclei within the same energy range were calculated. The experimental data can be predicted with greater precision when the cross sections derived from the proposed formula are compared to those derived from codes and earlier systematics. |
