Summary
Predictions for nucleon and neutron total cross sections were made using optical potentials. The results show good to excellent agreement with experimental data for carbon-12 and lead-208.
Area of Science:
- Nuclear physics
- High-energy physics
Background:
- Understanding nucleon-nucleus interactions is crucial for nuclear structure and reactions.
- Accurate cross-section data is essential for nuclear model validation.
Purpose of the Study:
- To predict nucleon and neutron total cross sections for 12C and 208Pb up to 300 MeV.
- To predict scattering cross sections at 65 MeV across a range of nuclei.
- To validate a theoretical model against experimental data.
Main Methods:
- Utilized coordinate space optical potentials.
- Employed full folding of effective nucleon-nucleon interactions.
- Incorporated realistic nuclear ground state densities.
Main Results:
- Achieved good to excellent agreement between predicted and existing experimental data.
- Demonstrated the predictive power of the optical potential model.
- Validated the model for both light (12C) and heavy (208Pb) nuclei.
Conclusions:
- The employed theoretical framework accurately describes nucleon-nucleus interactions.
- The coordinate space optical potential model is a reliable tool for predicting cross sections.
- The study provides valuable insights into nuclear reaction mechanisms.
