    Proton bombarded reactions of Calcium target nuclei
    Tel, E; Sahan, M; Sarpün, IH; Kavun, Y; Gök, AA; Depedelen, M
    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 Ca-40 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 Ca-40 target nuclei reactions (p,alpha), (p,n), (p,p) have been calculated using the semi-empirical formula Tel et al. [5].

    Reaction cross section calculation of some alkaline earth elements
    Tel, E; Kavun, Y; Sarpün, IH
    Reaction cross section knowledge is crucial to application nuclear physics such as medical imaging, radiation shielding and material evaluations. Nuclear reaction codes can be used if the experimental data are unavailable or are improbably to be produced because of the experimental trouble. In this study, there action cross sections of some target alkaline earth elements have been calculated by using pre-equilibrium and equilibrium nuclear reaction models for nucleon induced reactions. While these calculations, the Hybrid Model, the Geometry Dependent Hybrid Model, the Full Exciton Model, the Cascade Exciton Model for pre-equilibrium reactions and the Weisskopf-Ewing Model for equilibrium reactions have been used. The calculated cross sections have been discussed and compared with the experimental data taken from Experimental Nuclear Reaction Data library.

    Excitation Functions Calculations of the Charged Particle-Induced Nuclear Reactions on the 9Be Target
    Tel, E; Gok, AA; Sahan, M; Sarpun, IH; Kavun, Y; Aydin, A
    In this study, calculation of charged particles induced nuclear reactions of beryllium (Be-9) target nuclei have been investigated in the incident proton and alpha at energy range from threshold to 50 MeV. The excitation functions for Be-9 target nuclei reactions have been calculated by using PCROSS nuclear reaction calculation code. Weisskopf-Ewing model for equilibrium, calculations and the full exciton and cascade exciton models for pre-equilibrium calculations were used. Also, the semi-empirical calculations for (p,alpha) reactions have been done by using cross section formula updated with new coefficient developed by Tel et al. (Pramana Indian Acad Sci 74(6):931, 2010). The calculated results were compared with the experimental data for different energy levels ranging from 0.00 to 9.65 MeV taken from the literature.

    Particle induced nuclear reaction calculations of Boron target nuclei
    Tel, E; Sahan, M; Sarpün, IH; Kavun, Y; Gök, AA; Poyraz, M
    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 B-10 target nuclei reactions have been calculated by using PCROSS Programming code. The semi-empirical calculations for (p, alpha) 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.
