Summary
Chaotic scattering is relevant in heavy-ion reactions near the Coulomb barrier. This study models these collisions classically and quantum mechanically, linking chaotic features to experimental data anomalies.
Area of Science:
- Nuclear Physics
- Quantum Mechanics
- Chemical Physics
Background:
- Heavy-ion reactions near the Coulomb barrier are crucial for understanding nuclear interactions.
- Chaotic scattering phenomena offer a potential framework for interpreting complex reaction dynamics.
Purpose of the Study:
