Description des effets post-collisionnels dans les réactions d’ionisation d’atomes par impact d’électrons et de positrons

Abstract

In this work, both single and double ionization of atoms have been studied. For single ionization, we investigated ionization by electron and positron impact using the 3CW Z model to study charge effects on the argon atom. For double ionization, two theoretical models, BBK2DW and BBK2CW Z, were used. A first-order approximation was applied to these models on different atoms to study both distortion and post-collision effects.
