Nuclear reactions, which are very important from the point of view of human health, may occur during the production of the radiation sources, used in radiotherapy. The nuclear reaction data are needed in the radioisotope production procedure. The total cross section is also important in accelerator technology, in view of radiation protection and safety. In general, the significance of the cross section data for nuclear reactions in radionuclide production programs is firmly established. Gamma irradiation tracers can offer a large amount of information about the anatomy of different organs in the human body. The main purpose of this work was to compare the cross section of longer-shorter lived radionuclides. Theoretical excitation functions have been calculated with TALYS 1.6 nuclear reaction simulation code. The calculated results have been discussed and compared with the experimental data.
The main purpose of this study is the investigation of a cross section of proton induced nuclear reactions. The excitation functions of the reactions: 56Fe(p,2n)55Co 58Fe(p,2n)57Co, 111Cd(p,2n)110In, 112Cd(p,2n)111In, 125Te(p,2n)124I, 126Te(p,2n)125I, 68Zn(p,2n)67Gawere investigated. These reactions were studied as the resulting radioisotopes are used in medical applications. Theoretical excitation functions have been calculated with TALYS 1.6 nuclear reaction simulation code. The calculated excitation functions are compared with the experimental data.
In the nuclear medicine for the positron emission tomography, the injected positron emitter leads to two 511 keV γ-rays. One of the most promising radionuclides is 45 Sc. In this study, the main purpose was to investigate the excitation functions for the reactions 45 Sc (p, x). TALYS 1.6 nuclear reaction simulation code was used for the excitation functions. These calculated excitation functions have been discussed and compared with each other and with Experimental Nuclear Reaction Data Library (EXFOR).
Differential cross sections for elastic scattering of neutrons from 208 Pb target have been calculated with TA-LYS 1.6 nuclear code. Angular distributions were obtained for incident neutron energies of 5 to 96 MeV. The calculated data were compared with experimental results from literature. Calculations for angular distribution of elastic scattering of 208 Pb, made with TALYS 1.6 nuclear code, show good agreement with experimental data.
In general, the deep understanding of proton-induced reactions is a crucial step for the further development of nuclear reactions theory. However there has been an interesting focus in nuclear physics. Some applications require accurate nuclear reaction data of common cross sections and especially need the data of neutron and proton induced energy-angle correlated spectra of secondary particles, as well as double differential cross sections. Double-differential nucleon-production cross-sections of 56 Fe, 63 Cu and 90 Zr targets, bombarded with protons are calculated based on the nuclear theoretical models. Monte Carlo calculations with the TALYS 1.6 nuclear reaction simulation code are performed. Theoretical calculated results are compared with existing experimental data in EXFOR library.
