    Investigation of coulomb and pairing effects using new developed empirical formulas for proton-induced reaction cross sections
    (Maik Nauka/Interperiodica/Springer, 2010) Tel, Eyyüp; Aydın, E. Gamze; Aydın, Abdullah; Kaplan, Abdullah; Bölükdemir, Mustafa Hicabi; Okuducu, Şeref
    We have investigated Coulomb and pairing effects by using new empirical formulas including the new coefficients for (p, alpha) at 17.9 MeV, (p, np) at 22.3 MeV, and (p, n alpha) at 24.8 and 28.5 MeV energies. A new formula is obtained by adjusting Levkovskii's original asymmetry parameter formula and also Tel et al. formula for proton-induced reactions. The new coefficients by using least-squares fitting method for the reactions are determined. In addition, the findings of the present study are compared with the available experimental data.

    Production cross sections of medical In-110,In-111 radionuclides
    (Carl Hanser Verlag, 2010) Büyükuslu, Halim; Kaplan, Abdullah; Yıldırım, Gürcan; Aydin, Abdullah; Tel, Eyyüp; Bölükdemir, Mustafa Hicabi
    In this study, production routes of medical In-110,In-111 radio-nuclides produced by Cd-110(p, n)In-110, Cd-111(p, 2n)In-110, (112)cd(p, 3n)In-110, Ag-107(alpha, n)In-110, Ag-109(alpha, 3n)In-110, Cd-111(p, n)In-111, Cd-112(p, 2n)In-111, Cd-113(p, 3n)In-111, Cd-114(p, 4n)In-111, Ag-109(alpha, 2n)In-111, Ag-107(alpha, gamma)In-111 and In-113(n, 3n)In-111 reactions have been investigated up to 70 MeV incident particle energy. In these calculations, the pre-equilibrium and equilibrium effects have been investigated. The pre-equilibrium calculations involve the geometry dependent hybrid model and the cascade exciton model. The full exciton model has also been used to investigate the pre-equilibrium direct effects. Equilibrium effects are calculated according to the Weisskopf-Ewing model. The calculated results are compared with the experimental data taken from the literature.
