Semi-empirical systematics of (n,p) reaction cross sections at 14.5MeV neutron energy

Production and subsequent separation of 47Sc of nuclear medicine applications using neutron-induced reactions on different natural targets

“…Due to some difficulties in constructing fast neutron reaction experiments, insufficient cross section data for (n,p), (n,α) or (n,γ) reactions are available in the literature. Most of the existing literature data were found for incident neutron energy of about 14 MeV [29][30][31]. Some formulations for empirical formulae for fast neutron induced reactions were constructed and used to predict the excitation functions for neutron reactions on different existing stable isotopes.…”

Investigation of the pairing effect using newly evaluated empirical studies for 14–15 MeV neutron reaction cross sections

“…This allows an examination of the odd-even effect on basic nucleon-nucleus interactions by considering new experimental data and new cross section formulas developed by Tel et al for the (n, p), (n, d), (n, 2n), (n, t), and (n, α) reactions. The results obtained have also been investigated and compared with the other theoretical and experimental results proposed in earlier studies [21][22][23][24]. …”

Empirical formula on (n, 3 He) reaction cross sections at 14.6 MeV neutrons

“…On the other hand, the semi-empirical formulae are based on the analytical expressions for calculation of particle emission within the frame of the evaporation and preequilibrium exciton models (Aydın et al 2008a). Moreover, numerous empirical and semi-empirical formulae with different parameters for various nuclear reactions have been proposed by several authors (Aydın et al, 2008a(Aydın et al, , 2008bTel, 2014a, 2014b;Belgaid et al, 2005;Goyal and Kishore, 2012;Konobeyev and Korovin, 1995;Challan and Fayez-Hassan, 2014). In this work a new empirical formula has been presented to describe the (n, 3 He) reaction cross sections at 14.6 MeV energy.…”
