Comparative Theoretical Study of (e,3e) on Helium: Coulomb-Waves versus Close-Coupling Approach

Kheifets, Anatoli; Bray, Igor; Berakdar, J.; Dal Cappello, C


We discuss common features and differences in the fully differential cross sections (FDCS) for the electron-impact double ionization of He evaluated using the convergent close-coupling (CCC) method and various methods that utilize the three-body Coulomb wavefunctions (3C and C4FS). The calculations are restricted to the first Born approximation with respect to the interaction of the fast projectile with the target. In contrast to the similar (γ, 2e) reactions, where predictions of all the above...[Show more]
