Niobium-90 radionuclide is one of the promising candidates for the positron emission tomography (PET) technique. In this study, 90 Nb excitation functions via 90 Zr(p,n) and nat Zr(p,xn) reactions were computed using the TALYS-1.95 code based on phenomenological and microscopic level density models. The MCNPX simulation code was used for each case. Moreover, the target thicknesses were obtained using the SRIM-2013 code and the theoretical and simulation-based production yields of the 90 Nb were evaluated. The experimental production yield amounts of about 72.68 and 126.7 (both in MBq/μAh) for 90 Zr(p,n) and nat Zr(p,xn) reactions in the corresponding optimal energy windows were attained by our experiments respectively., (Copyright © 2021 Elsevier Ltd.

The main goal of this study is the production investigation of the 111 In as a diagnostic and mighty radionuclide in nuclear medicine especially in the Single Photon Emission Computed Tomography (SPECT) technique. Excitation functions based on four main phenomenological level density models were evaluated for the induced reactions; namely, 109 Ag(α,2n), 110 Cd(d,n), 111 Cd(p,n), 112 Cd(p,2n), nat Cd(p,xn) and nat Cd(d,xn) using the TALYS-1.8 and EMPIRE-3.2 nuclear codes. Furthermore, simulation code was used for the mentioned processes and, also, the 111 In production yield predictions in each reaction were done. Finally, in order to certify the above calculation outcomes, a comparison with the existing data which were taken from EXFOR database was implemented., (Copyright © 2020 Elsevier Ltd.

Excitation functions based on level density were calculated for proton-induced on yttrium-89 using the TALYS-1.8 code. Hence, production cross-section of the 89 Y(p,x) 86,88,89g Zr, 86g,87g,88g Y, 85g Sr, and 84g Rb were computed up to 50 MeV. In this study, the constant temperature model alongside the Fermi Gas model (CGCM) was employed as a default model. For this reason, the a-parameter as an essential parameter in the Fermi Gas formula was modified to obtain the best result. Besides, the Back-shifted Fermi Gas Model (BSFGM) and the Generalized Superfluid Model (GSM) are presented to the deliberation. The outcomes of cross-sections were compared with the experimental data approaching regarding desired consequences., (Copyright © 2019 Elsevier Ltd. All rights reserved.)
