The effects of plasma electrons and ions are treated separately. While ions are considered static and within two different ion-dynamics models, the collision approximation is used for electrons in two different versions: a perturbative Born approximation, and an effective two-particle T-matrix approach based on convergent-close coupling calculations. The latter is able to treat strong electron-emitter collisions consistently.
