Abstract

In this work, the production of I111n radionuclide has been investigated theoretically via heavy-ion fusion reactions of two stable nuclei: C37l+G74e, M26g+R85b, S30i+B81r, and C46a+C65u reactions. Fusion cross-sections, barrier distributions, and potential energies on mutual orientations in the reactions planes of all reactions have been researched in detail around the barrier region via a coupled channel (CC) model using different codes. First of all, the most suitable codes and calculation parameter sets were determined through the C37l+G74e reaction, whose experimental data were available. The compatibility of the calculations via NRV knowledge base, CCFULL, CCDEF codes, and Wong’s formula with experimental data was analyzed. Barrier distributions and cross-sections for heavy-ion fusion reactions have been investigated with miscellaneous codes and vibrational-rotational nuclei combinations for interacting nuclei. Afterward, calculations were made with the determined parameter values for new reaction suggestions (M26g+R85b, S30i+B81r, and C46a+C65u reactions) and the results were compared. This study aims to suggest the new reaction combinations for the production of 111In radionuclide, to explore the impacts of different calculation codes and nuclear parameter combinations on the heavy-ion fusion cross-sections and barrier distributions, to demonstrate that the results are reliable, and to emphasize the importance of developing these studies in the preparation of new experiments.

Highlights

The interaction between heavy ions is defined as the interaction of two nuclei moving at a central potential of a short-orbit nuclear interaction and a long-orbit Coulomb repulsive effect [1,2,3]
We focused on establishing the theoretical frameworks for 111 In radionuclide over the coupled channel model in the heavy-ion fusion reaction calculations
We set our parameters according to experimental data and rearranged each parameter for coupled channel model and dynamic deformations and rotation set

Summary

Introduction

The interaction between heavy ions is defined as the interaction of two nuclei moving at a central potential of a short-orbit nuclear interaction and a long-orbit Coulomb repulsive effect [1,2,3]. The fusion reactions of heavy ions have attracted the attention of nuclear physicists, who have subsequently performed theoretical and experimental studies in recent years [4,5,6,7]. This enhancement in attention is owing to the day-by-day increase in heavy-ion accelerator research areas with wide and usable energy intervals. These heavy-ion reactions offer the possibility to produce excited nuclei. All this research leads to the development of nuclear models that aim to explain the structure of the nucleus
