Etude de la double ionisation d'atomes par impact d'électrons : élaboration et utilisation du modèle A6C

Abstract : This work is about the theoretical study of the double ionization of atoms by electron impact. A model including exchange effects between the incoming electron and the two active electrons of the target is described. Each electron in the continuum (the scattered one and the two ejected ones) is described by a coulomb wave which takes into account for the interaction with the residuel nucleus. The interactions between each electron in the continuum have been included by Gamow factors (A6C model). A first part is about the double ionisation of helium and a comparison has been made with recent experiments of LAHMAM-BENNANI et al. then, in a second part, our model has been compared to the recent experiments of LAHMAM-BENNANI et al about the double ionization of argon (direct double ionization + Auger effect).
