“…Full exciton model calculations have been done with PCROSS code [27] that used the initial exciton number as n o =1 of 1 neutron and 0 hole [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. Theoretical calculations of 10 B(p,α) equilibrium and pre-equilibrium reactions are compatible with each other as seen in Fig.…”

Abstract.Boron is usable element in many areas such as health, industry and energy. Especially, Boron neutron capture therapy (BNCT) is one of the medical applications. Boron target is irradiated with low energy thermal neutrons and at the end of reactions alpha particles occur. After this process recoiling lithium-7 nuclei is composed. In this study, charge particle induced nuclear reactions calculations of Boron target nuclei were investigated in the incident proton and alpha energy range of 5-50 MeV. The excitation functions for 10 B target nuclei reactions have been calculated by using PCROSS Programming code. The semi-empirical calculations for (p,α) reactions have been done by using cross section formula with new coefficient obtained by Tel et al. The calculated results were compared with the experimental data from the literature.

Abstract:In this study, proton bombarded nuclear reactions calculations of Calcium target nuclei have been investigated in the incident proton energy range of 1-50 MeV. The excitation functions for 40 Ca target nuclei reactions have been calculated by using PCROSS nuclear reaction calculation code. Weisskopf-Ewing and the full exciton models were used for equilibrium and for pre-equilibrium calculations, respectively. The excitation functions for 40 Ca target nuclei reactions (p,α), (p,n), (p,p) have been calculated using the semiempirical formula Tel et al. [5].

“…Systematics of cross-sections has a special importance as an additional tool for the cross-section evaluation [1][2][3]. Many studies on systematics of cross-sections have been done in the literature [4][5][6][7][8][9][10][11][12][13][14][15][16]. Formulas obtained from this systematics have been used in the present study for Li and Be target nuclei irradiated with neutrons and alphas.…”

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.
