Explore how quantum theory explains positron collisions with hydrogen using a rigorous bound‑giving method.
This book introduces the Kato variational approach to scattering by a compound system and shows how polarization effects can dramatically alter outcomes at low energies.
In a clear, practical setting, the text discusses how to bound scattering quantities and how to handle the long‑range Coulomb potential that challenges calculations. It lays out the true problem, the role of polarization, and the value of combining variational ideas with bound‑type results to gauge accuracy.
- Learn how the Kato method is applied to positron scattering from hydrogen
- See why polarization can turn expectations from repulsion to attraction in low energies
- Understand how trial functions are built and tested for reliability
- Get a sense of the limitations and the need for multiple checks in bound computations
Ideal for readers of advanced quantum mechanics and theoretical scattering who want a practical, grounded treatment of a representative two‑body–plus–field problem.
