Double ionization of helium by 2-keV electrons in equal- and unequal-energy configurations
(American Physical Society, 2016-03)
We present theoretical and experimental fully differential cross sections, in coplanar scattering geometry, for the double ionization of helium by electron impacting at 2 keV. The observed structures for both equal and ...
Multiple ionization of Argon by Helium ions
(Iop Publishing, 2016-08)
We apply the continuum distorted-wave eikonal initial state and the independent electron model to describe the multiple ionization of Ar by He2+ and He+ in the energy range 0.1–10 Mev amu–1. Auger-like post collisional ...

Double ionization of helium by proton impact: from intermediate to high momentum transfer
(Springer, 2017-05)
We study theoretically the double ionization of helium by 6 MeV proton impact. For suchfast projectiles, when considering the projectile-target interaction to first order, the four-body Schr¨odingerequation reduces to ...
Double ionization of helium by fast electrons with the Generalized Sturmian Functions method
(Iop Publishing, 2015-02)
The double ionization of helium by high energy electron impact is studied. The corresponding four-body Schrödinger equation is transformed into a set of driven equations containing successive orders in the projectile–target ...
Discrepancy between theory and experiment in double ionization of helium by fast electrons
(American Physical Society, 2015-01)
We compute fully differential cross sections for double ionization of helium by electrons, within the high-impact-energy and low-momentum transfer regimes, using the generalized Sturmian functions approach. Our results are ...
Ionization of helium by fast and highly charged ions
(Institute of Physics Publishing, 2007-03)
We present CDW-EIS theoretical calculations for the projectile deflection in single ionization of Helium by heavy-ion impact as a function of ionized electron energies. These calculations account for the projectile-residual ...
Double ionization of helium by ion impact: second Born order treatment at the fully differential level
(Institute of Physics, 2015-01)
In this work, a theoretical study of the double ionization of He by ion impact at the fully differential level is presented. Emphasis is made in the role played by the projectile in the double emission process depending ...
Fully differential cross sections in single ionization of helium by ion impact: Assessing the role of correlated wave functions
(Elsevier Science, 2008-02)
We study the effect of final state dynamic correlation in single ionization of atoms by ion impact analyzing fully differential cross sections (FDCS). We use a distorted wave model where the final state is represented by ...
