Abstract

This paper aims to examine the production of diagnostic radioisotopes used in Single Photon Emission Computed Tomography (SPECT) using six different level density models. The cross-section curves and the integral yield of reaction processes were calculated using the TALYS code and X-PMSP program for the level density models in the energy region of 1–100 MeV with the constant particle beam current of 1 [Formula: see text]A and irradiation time of 1 h. The results have been compared with the experimental and the data recommended in the literature. To overcome the lack of experimental and theoretical yield data of reaction processes, the integral yield results obtained by the cross-sections and mass stopping powers in the production of radioisotopes contributed new insights to the nuclear data in the literature. Based on the obtained data, the calculated results have been discussed, and the obtained new data, appropriate energy regions and reaction processes for the production of diagnostic radioisotopes have also been recommended.
