The aim of this study is to obtain a new semi-empirical formula for (alpha, p) reactions concerning the possible usage areas of this reaction type, where the fusion reactor studies could be pointed as one of them. The formula development studies have been performed by considering the existing semi-empirical formula modification studies in the literature where an absence of (alpha, p) reaction has been realized. The suitable experimental data, existing on the EXFOR database, have been used to generate the (alpha, p) reaction cross-section systematics in the energy range of 19 +/- 1 MeV. Also, statistical analyses have been performed and the correlation coefficients (R-2) generated by fit parameters have been given.
