| Titre: | Modeling of initial and final correlation effects in double ionization of noble gases and methane / |
| Auteur(s): | Sakhraoui, Wafa |
| Date de publication: | 2025 |
| Description: | This thesis investigates the double ionization of atoms and molecules by electron impact, a key process to understanding particle-matter interactions. After introducing the fundamentals of scattering theory and cross-section concepts, the study focuses on double ionization mechanisms (shake-off, two-step 1, and two-step 2), emphasizing the critical role of electron correlation. Several theoretical models, including BBK (3C), DWBA, and 2CWG, are employed to describe the final-state electron dynamics. Applications to atomic (Neon, Krypton) and molecular (CH₄) targets demonstrate good agreement with experimental data, especially when correlation and distortion effects are included, validating the theoretical approach. |
