Abstract
In this work, the reaction cross-section for neutron-induced reactions on 127I isotope was calculated using EXIFON code in the energy range of incident particle from 0 MeV to 30 MeV. The code is based on an analytical model for statistical multistep direct and multistep compound reactions (SMD/SMC model). In order to see the effect of nuclear structure on cross sections, the calculation was done using nuclear shell structure effect and without considering shell structure effect. Obtained results and statistical analysis showed that shell structure effect does not give significant changes to the cross-section at considered energy ranges. This shows that EXIFON code is a good tool for investigation of nuclear reaction cross section and is useful in the production of the radioisotopes of Iodine, Antimony and tellurium of high purity and in an efficient manner using cyclotron or nuclear reactors, these isotopes have potential application for field of medical science especially for diagnostics and therapeutic purposes.
Highlights
The artificially produced radioactive isotopes are important for many different applications [1]
Excitation function is defined as the graphical plots of cross-section against the energy of the incident particle, it is an important parameter in nuclear data analysis describes the probability that nuclear reactions can occur at particular energy of incident particle
A nuclear reaction in the intermediate-energy region is a matter of interest in some fields of science and technology such as medical radionuclide production
Summary
The artificially produced radioactive isotopes are important for many different applications [1]. Radioactive isotopes play an important role in the field of medical science in terms of beneficial applications in both diagnosis and therapy purposes [2]. Radioisotope production for nuclear medicine is important because of its common use in tomography devices. The radionuclide of iodine is used for these purposes This radionuclide plays an important role in medical applications and research. The long-lived 125I isotope is used as a source for internal radiotherapy, bone dosimetry and a biological tracer [3] Another iodine radionuclide 122I is a very short-lived isotope and used in PET for brain blood-flow studies [4]
