“…The interaction between heavy ions is simply 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.…”

In this work, the production of 111In radionuclide has been investigated theoretically via heavy-ion fusion reactions of two stable nuclei: 37Cl+ 74Ge, 26Mg+ 85Rb, 30Si+ 81Br, and 46Ca+ 65Cu 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 37Cl+ 74Ge 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 (26Mg+ 85Rb, 30Si+ 81Br, and 46Ca+ 65Cu 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.

“…Fusion processes at energies near the Coulomb barrier can be considered as a multidimensional barrier penetration problem [5][6][7][8]. The multidimensional barrier penetration part can be explained by disentangling the coupled channel (CC) model equations [9][10][11][12][13]. Nevertheless, on account of complex reaction mechanisms, it is obligatory to reckon with a great number of channels that are difficult to perform in the calculation model.…”

For the vibrational and rotational coupling effect, the parameters of the models used respectively are given.…”

“…For the vibrational and rotational coupling effect, the parameters of the models used respectively are given. For spherical reaction systems (vibrational coupling effect), the amplitude of the barrier distribution ascends with the charge product of the reaction system, while for the deformed reaction systems (rotational coupling effect), besides the charge product of the reaction system, the amplitude of the barrier distributions is also related to the static deformation coefficients of the projectile and the target [13][14][15][16]. In general, the CC model for the parameters of the barrier distribution works quite well in defining cross-sections and can provide useful information about cross-section estimates [16][17][18].…”

This work has been carried out to obtain and inspect of At 211 radionuclide through fusion reaction. Cross-sections for fusion reaction have been calculated with different interaction combinations and excitations for F 19 + Os 192 and O 18 + Ir 193 reactions. All calculations have been performed on NRV Knowledge Base, CCFULL code, and Wong's Formula. Firstly, we assigned reaction parameter values taking into account the compatibility with the experimental data F 19 + Os 192 reaction. Afterward, to enrich studies on At 211 radionuclide, we proposed O 18 +Ir 193 reaction which did not have experimental data in the literature with the method and parameter values we determined. We examined the effects of phonon excitations in projectile and target nuclei on fusion cross sections and barrier distributions. With our research, we showed that the coupled channel model and the calculation codes used to explain the fusion cross-section data and barrier distributions well. This research sheds light on the importance of analyzing important medical radionuclides such as At 211 by heavy-ion fusion reactions and encourages new researches.
