| Aims of the course | The aim of the course is to present the actual methods and models of the interactions of atomic particles with solid surfaces. The main aim is to analyze the two-state vector model of the Rydberg state population of multiply charged ions. | |||||||||
| Learning outcomes | Students are able to follow the scientific results in the ion-surface research field. Also, they are able to formulate the basic expressions for the calculation of the intermediate and final probabilities. The course yields the basic knowledge for the understanding of the interactions with conduction surfaces and other type of surfaces. | |||||||||
| Contents of the course | ||||||||||
| Lectures | 1. Review of methods and models. 2. Quantum mechanics and the two-state model (quantum teleology). 3. Mixed flux (probability amplitude and rate). 4. Interaction potentials in the ion-surface system (atomic potentials, image forces). 5. Dielectric response theory of the surface. 6. Electron capture (trajectory perpendicular to the surface and grazing incidence). 7. Hamiltonians, preselection and postselection, dynamic generalization. 8. Teleological model of neutralization. 9. Wave functions of the active electron and mixed flux (phase integral method, etalon equation method, bifurcation of the solutions). 10. Phase portrait of the mixed flux and self organization. 11. Population of the Rydberg states of large angular momentum. 12. Reionization processes. 13. Intermediate population probabilities and rates (neutralization distances, connection with the classical over-barrier model and experiments). 14. Final probabilities (distributions over electron energies and angular momentum). 15. Final distributions and their role in the radiative transitions on the large time-scale. | |||||||||
