“…Namely, the influence of the Coulomb force between the charged particles of target nuclide and the projectile proton particle can be given by the proton Coulomb effect cross section for nuclear reactions of incident proton particles. Based upon the studies of [11,12,15], we assumed that the empirical equation for (p,α) cross sections is approximately written as following,…”

“…The coefficients "𝐶" and " 𝑎" obtained from least squares method are the fitting parameters [15]. Besides, the asymmetry term and Coulomb effects were investigated for performing complete description of (d,n) and (d,2n) cross sections [11,12]. In this framework we obtained (p,α) empirical cross section formulas by considering the original formula of Levkovskii on the calculations of cross section for (p,α) nuclear reactions at 17.9 MeV.…”

“…Obtaining systematics at different projectile energies is an important part of studies concerned with the cross section calculations on various reaction channels. Thereby, empirical systematics have been widely used at present for nuclear cross section predictions [7,[9][10][11]. Particularly, the systematics play an important role in determining excitation functions at incoming energies of which there are no experimental cross section.…”

Nuclear cross section data are needed in various applications such as radiation therapy, astrophysics, radioisotope production, fusion and fission. The systematics play a very important role in determining cross sections on neutron- and proton-induced reactions at incoming energies of which there are no experimental values. So, empirical systematics have been extensively used at present in the studies on cross section calculations. In this paper, we proposed empirical cross section formulas considering Q–value dependence on (p,α) reactions at proton energy of 17.9 MeV. The present formulas including Coulomb and odd-even effects are based on the statistical theory. In addition, these formulas are a modification to the Levkovskii’s original asymmetry parameter formulas for neutron induced reactions and the Tel et al.’s empirical formulas for proton reactions. Fitting parameters of formulas were determined by least-squares fitting to experimental excitation function data. It is seen that new empirical formulas give good fits with (p,α) experimental cross section values in the literature at 17.9 MeV.
