In this study, by using the pre-equilibrium and equilibrium reaction mechanisms, the cross-sections of (n, p) reactions on S-32, Zn-64, Zn-67, Y-89, Zr-90 and Eu-153 targets have been calculated. The excitation functions of (n, p) reactions on S-32, Zn-64, Zn-67, Y-89, Zr-90 and Eu-153 targets by using the hybrid model, the geometry dependent hybrid model and the exciton model of pre-equilibrium reaction mechanism at the energies in the range 1-20 MeV have been investigated. To investigate the equilibrium effects, the Weisskopf-Ewing model is used. The proton emission spectra of (n, xp) reactions by 14.6, 14.8 and 14.8 MeV neutron i . . .ncident energies, respectively, on S-32, Y-89 and Zr-90 targets are also investigated using the same models. The obtained results have been discussed and compared with the experimental results. (c) 2012 Elsevier Ltd. All rights reserved Daha fazlası Daha az

Investigation of pre-equilibrium (PEQ) and equilibrium (EQ) effects on proton induced reactions for production of radioisotopes are very important. Therefore, in this study, we have calculated the PEQ and EQ cross-sections for 67Zn(p,n)67Ga, 68Zn(p,2n)67Ga, 82Kr(p,2n)81Rb, 111Cd(p,n)111In, 112Cd(p,2n)111In, 123Te(p,n)123I, 124Te(p,2n)123I, 124Te(p,n)124I and 124Xe(p,2n)123Cs reactions for production diagnostic radioisotopes. Calculations have been performed by using the hybrid model, geometry dependent hybrid model and full exciton model of PEQ reaction mechanism with 1-40 MeV proton incident energy. We have also investigated the EQ . . . effects on these reactions using the Weisskopf-Ewing model in the same energy range. The excitation functions including the PEQ and EQ effects on these reactions are evaluated by using the ALICE/ASH (2006) and the TALYS 1.4 (2011) codes. Our results have shown that using these codes is suitable for production diagnostic isotopes mentioned above. To obtain excitation functions for producing the diagnostic radioisotopes the PEQ mechanism has been found more dominant than that of the EQ. The results are discussed and compared with the available experimental data. © 2013 Akadémiai Kiadó, Budapest, Hungary Daha fazlası Daha az
