Photonuclear reactions play an important role in many different subfields of nuclear astrophysics, and fields, such as nucleosynthesis applications. The photonuclear reaction cross sections, especially the photoneutron reaction cross sections, are the fundamental properties of nuclear systems. In this study, theoretical evaluation of photoneutron reaction cross sections for 27 ≤ A ≤ 238 targets (^{27}Al, ^{96}Mo, ^{181}Ta, ^{238}U) have been investigated in the incident photon energy range of 7-35 MeV. Monte Carlo code TALYS 1.6 was used to calculate the photoneutron cross sections. The results are compared with the earlier experimental reports in literature and the cross section data in the TENDL-2013 nuclear reaction data library, based on subsequent versions of the TALYS nuclear code system. The photoneutron cross section results and the effects of the mass number of target nuclei are discussed.

Many radioisotopes are used in nuclear medicine diagnostics and therapy. Co-57, In-111 and Tc-99m isotopes are widely used in nuclear medicine and are successfully implemented in renal imaging. In this work, the cross section calculation of the (p, 2n) reaction, which is necessary for production of the nuclei of Co-57, In-111, Tc-99m, were calculated using TALYS 1.6 nuclear reaction code. The calculated cross sections were compared with the experimental data from the EXFOR.

Myocardial perfusion scintigraphy, is an imaging technique used for diagnostics of coronary artery disease in people by evaluating the amount of blood reaching the heart muscle. During myocardial perfusion scintigraphy a radiopharmaceutical is injected into the patient and after a period of time a series of images are acquired using gamma camera rotated by 180° around the patient. The distribution of the radiopharmaceutical is then determined using the technology of single photon emission computed tomography. The most commonly used agents in myocardial perfusion scintigraphy radiopharmaceuticals are Tl-201 and Tc-99m. The production of such radiopharmaceuticals containing Tl-201 and Tc-99m has been examined by this study. This study was performed using Monte Carlo nuclear reaction simulation code TALYS 1.6.

Positron emission tomography is an imaging method which plays an important role in the diagnosis and monitoring of cancer cells using radioactive substances. In this study (p,n) reaction cross sections of some radionuclides (Cu-61, Ga-66, Br-76) were calculated using Talys 1.6 nuclear simulation code. The calculated cross-sections were compared with experimental values taken from EXFOR.

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 ⁵⁶Fe, ⁶³Cu and ⁹⁰Zr 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.

Knowledge of the cross sections of reactions of charged particles with target material is needed to understand well the mechanisms of nuclear reactions. One of the main application fields of nuclear technology and nuclear reactions is medicine. Radioisotopes are used in medicine and production of these radioisotopes is important. In the production processes, the cross sections must be known. For this purpose, in this study, theoretical cross sections of production of In isotopes by alpha irradiation have been calculated using Talys 1.6 nuclear reaction simulation code. The obtained results are compared with the existing experimental data.
