Effects of theoretical models on the production cross-section calculations of some non-standard positron emitters

Theoretical studies and their outcomes, such as cross-section data, become more valuable in the cases where the experimental studies are not possible to take place. In this study, by considering the importance of the medical radioisotopes, especially the positron emitters, and the benefit of theoretical calculation results, production cross sections of Cu-61, Ga-66, As-72, Se-73, and Br-76 non-standard positron emitters via alpha-induced reactions were examined by utilizing level density models and alpha optical model potentials. In accordance with the aims of the study, all calculations were done by using a computation code TALYS v1.9, for the available six level density models and the eight alpha optical model potentials from the code. To investigate the consistency of the calculation results with the available experimental data, taken from the Experimental Nuclear Reaction Data (EXFOR) Library, a mean-weighted deviation analysis was used.
