摘要

This study presents a comprehensive investigation into the production of 139Pr, encompassing both theoretical and experimental approaches. The theoretical aspect of the research involves an in-depth exploration of various excitation functions for potential reactions leading to the production of 139Pr. Using the TALYS-1.9 code, a wide array of reactions involving different targets (Ce, La, Nd, and Pr) and projectiles (protons, deuterons, and alphas) was analyzed. The results from the TALYS code revealed that 140Ce served as the most promising target. Subsequently, the SRIM code was employed to determine the optimal thickness of the 140Ce target for the proposed reactions. In the experimental approach, the preparation of the target was done using tablet method, resulting in the creation of four disk-shaped tablets. These tablets were then subjected to irradiation with a proton beam in the energy range of 30 MeV. The outcome of this comprehensive study culminated in a substantial production yield of 34.2 mCi/u.A.h, demonstrating excellent agreement with similar experimental processes conducted by other researchers.
