Optical potential analysis of antiproton-nucleus data at low energy

The study of antiproton-nucleus interactions at low and very low energies is important for under- standing nuclear dynamics and interactions. In this work, we analyze antiproton elastic scattering and annihilation cross-section data using an optical model approach. By employing the Woods- Saxon potential, we extract meaningful parameters to describe the interaction and provide insight into momentum dependence. The results indicate good agreement with experimental data, while also suggesting hidden dependencies on momentum in potential parameters. Future improvements involve refining computational techniques and exploring alternative parameterizations to achieve more precise modeling.
