    New calculations of excitation functions of some positron emitting and single photon emitting radioisotopes
    (Carl Hanser Verlag, 2008) Aydin, E. G.; Tel, E.; Kaplan, A.; Aydin, A.
    In this study, new calculations of the excitation functions of (56)Fe(p,2n)(55)Co, (58)Fe(p,2n)(57)Co, (60)Ni(pn)(60)Ca, (62)Ni(p,2n)(61)Cu, (68)Zn (p,2n)(67)Ga, (72)Ge(p,n)(72)As, (82)Kr(p,2n)(81)Rb, (124)Xe(p,2n)(123)Cs, (112)Cd(p,2n)(111)In and (203)Tl(p,3n)(201)Pb reactions have been carried for incident proton energies up to 50 MeV. In these calculations, the pre-equilibrium and equilibrium effects have been investigated. The pre-equilibrium calculations involve the newly evaluated geometry-dependent hybrid model, hybrid model and the cascade exciton model. Equilibrium effects are calculated according to the Weisskopf-Ewing model. The calculated results tire compared with the experimental data taken from the literature.

    Spallation neutron emission spectra in medium and heavy target nuclei by a proton beam up to 140 MeV energy
    (Pergamon-Elsevier Science Ltd, 2009) Kaplan, A.; Tel, E.; Aydin, E. G.; Aydin, A.; Yilmaz, M.
    In this study, neutron-emission spectra produced by (pxn) reactions for some spallation neutron target nuclei such as (65)Cu, (204.206.207.208)Pb, (209)Bi, (232)Th and (238)U have been calculated by a proton beam up to 140 MeV. Multiple pre-equilibrium mean free path constants from internal transition for (204,208)Pb (p, xn) neutron emission spectra have been investigated. In the calculations, pre-equilibrium effects were calculated by using new evaluated hybrid model and geometry dependent hybrid model, full exciton model and cascade exciton model. The reaction equilibrium component was calculated by Weisskopf-Evving model. The obtained results have been discussed and compared with the available experimental data and found agreement with each other. (C) 2009 Elsevier Ltd. All rights reserved.
