“…Pai and Andrews [36] added an effective Q-value, defined as an energy of nuclear reaction. Habbani and Osman [35] proposed systematic based on the statistical model including odd-even effect for (n,p), (n,a), and (n,2n) reaction cross-sections for 14.5 MeV neutrons. Tel et al [28] obtained a new empirical (n,p) cross-section formula taking shell model and pairing effects into account.…”

“…Broeders and Konobeyev [10] proposed a semi-empirical formula with contribution of both non-equilibrium and equilibrium proton emissions for (n,p) reaction cross-section at 14.5, 20, and 30 MeV neutron energies. Many studies on (n,p), (n,a) and (n,2n) reaction cross-section formulas for 14-15 MeV neutrons have been made by the authors [7,[30][31][32][33][34][35][36][37]. These formulas are given for (n,p), (n,a) and (n,2n) reactions in Tables 1, 2 and 3, respectively.…”

The Comparison of (n,p), (n,α), (n,2n) and (α,n) Reaction Cross-Sections for 7Li and 9Be Target Nuclei

et al. 2016

The knowledge of the cross-section is important especially for the fusion and fission reactor technology. In the absence of experimental data or in the difficulty of measuring data, theoretical predictions of nuclear crosssection data are needed to be improved using model calculations or semi-empirical formulas and to be compared with model and formulas to obtain sensitive approaches. In this work, for 7 Li and 9 Be target nuclei used as blanket materials in fusion reactors, (n,p), (n,a), (n,2n) and (a,n) reaction cross-section data have been evaluated by using some available empirical and semi-empirical cross-section formulas. The (n,p), (n,a), (n,2n) and (a,n) reaction crosssection formulas developed for medium and heavy mass nuclei by some scientist in literature are applied to 7 Li and 9 Be light nuclei and then results obtained from any systematics are compared with each other and the existing experimental data.

“…In the formula, droplet model of Myers and Swiatecki [16] was used for Q(n,α) calculations [4]. Habbani and Osman proposed systematics for (n,p), (n,α), and (n,np) reaction cross-section for 14.5 MeV neutrons and the obtained formula was based on the statistical model with the Q-value and odd-even effect [6]. Tel et al obtained a new empirical (n,p) cross-section formula tak-B-129 ing shell model and pairing effect into consideration by modifying Levkovskii's empirical formula [7].…”

“…A great number of empirical and semi-empirical crosssection formulae have been proposed for different target nuclei irradiated with uncharged neutron and charged particle at the specific energies [1][2][3][4][5][6][7][8][9][10][11][12]; however, there is not any study on cross-section systematics of alphainduced reactions. As a result of alpha-induced reactions, in particular the production of significant medical radioisotopes used in nuclear medicine occurs [13][14][15].…”

Semi-Empirical Formula with New Coefficients of the (α,n) Reaction Cross-Section

2015

A new modified semi-empirical formula including non-elastic scattering and Coulomb effects for the (α,n) reaction cross-section was obtained. The available experimental data were used to get the (α,n) reaction cross-section systematics. The dependence between the cross-section and asymmetry term was discussed for (α,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.
