Özet

A new modified semi-empirical formula including non-elastic scattering and Coulomb effects for the (alpha,n) reaction cross-section was obtained. The available experimental data were used to get the (alpha,n) reaction cross-section systematics. The dependence between the cross-section and asymmetry term was discussed for (alpha,n) reaction at 18.5 +/- 3 MeV energies classifying the target nuclei into odd Z-even N and even Z-even N. The coefficients of determination (R-2) for all classifications were detected to exhibit the amount of relation between asymmetry term and cross-sections obtained from the modified semi-empirical formula with new coefficients.
