Exploring Heavy-Ion Fusion as a Pathway for Production of Indium-111

Pathways for the production of indium-111 (¹¹¹In) radionuclide, a radioisotope commonly used in medical imaging, via heavy-ion fusion is explored at energies around the barrier with the interaction potential taken as the sum of Coulomb and Wood-Saxon form. In particular, the following reactions have been studied: ³⁷Cl + ⁷⁴Ge, ²⁶Al + ⁸⁵Kr, ²¹Ne + ⁹⁰Y along with other pathways not listed here. Fusion cross-sections and barrier distributions are calculated via the one-dimensional penetration model and the channel coupling model implemented via NRV code. The aims of the study are to suggest new reaction combinations for the production of ¹¹¹In radionuclide, compare different models, and explore the impact of deformation parameters on the heavy-ion fusion cross-sections and barrier distribution.
