Summary
This study presents an optimized evaluation of proton-induced reactions on Cadmium-111 using the TALYS code and an iterative Bayesian Monte Carlo framework. The new nuclear data improves accuracy for radioisotope production.
Area of Science:
- Nuclear physics
- Nuclear data evaluation
- Computational physics
Background:
- Accurate nuclear reaction data are crucial for optimizing radioisotope production.
- Proton-induced reactions on Cadmium-111 are important for specific applications.
Purpose of the Study:
- To evaluate proton-induced reaction data on Cadmium-111 (¹¹¹Cd) from 1 to 100 MeV.
- To improve the accuracy of nuclear data for radioisotope production.
Main Methods:
- Utilized the TALYS code system within an iterative Bayesian Monte Carlo (iBMC) framework.
- Simultaneously varied nuclear reaction models and parameters in TALYS.
- Compared calculated cross sections and angular distributions with experimental data from EXFOR.
Main Results:
- Achieved a targeted convergence of 5% for the evaluated nuclear data.
- The final evaluated file shows favorable comparison with experimental data and existing libraries (TENDL-2021, JENDL5.0).
Conclusions:
- The iBMC framework provides a robust method for nuclear data evaluation.
- The evaluated ¹¹¹Cd proton-induced reaction data are suitable for radioisotope production optimization.
