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 ...
Fivefold differential cross sections for electron-induced double ionization of outer and inner valence (1t2 and 2a1) molecular orbitals of CH4
(Elsevier Science, 2016-01)
We report in this work theoretical differential cross sections for the double ionization of oriented methane molecular subshells, namely, the 1t2 and 2a1 levels, impacted by 1 keV electrons. The present calculations are ...
Theoretical study of the double ionization of the He isoelectronic sequence by protons and antiprotons
(Elsevier Science, 2012-07)
We evaluate the fully differential cross sections (FDCS) for the double ionization of the He-isoelectronic sequence by proton and antiproton impact. We use a distorted wave model recently introduced by the authors based ...
Evaluation of differential cross sections using classical two-active electron models for He
(Springer, 2019-01-10)
Differential cross sections for charge-exchange and single and double electronic emission in collisions of protons with He atoms at intermediate impact energies are theoretically evaluated by means of two classical trajectory ...
Double ionization of He by ion impact: Second-order contributions to the fully differential cross section
(American Physical Society, 2014-06)
In this work, we present a second-order Born series treatment for the double ionization of He by ion impact. In particular, we show that the well-known independent events and independent electron models naturally result ...
Generalized Sturmian Functions applied to double continuum problems
(IOP Publishing, 2015-04)
The Generalized Sturmian Functions method aims to deal with atomic physics
problems. It has seen application to two and three?body problems, and its flexibility enables one to work with bound systems as well as with ...
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 ...
Fully and double differential cross sections for the single ionization of H2O by bare ion impact
(IOP Publishing, 2014-01)
A theoretical study of fully differential cross sections for the single ionization of H2O by collisions with H+, p¯ − and He2+ at an impact energy of 2 and 6 MeV amu−1 is presented. We work in terms of the Born-3DW model, ...
Electron emission in ionization of adenine molecule induced by 5 MeV/u bare C ions
(Springer, 2020-08)
The double differential cross sections (DDCS) of electron emission in ionization of adenine molecule (C5H5N5) induced by 5 MeV/u bare C ions are measured using the electron spectroscopy technique. Emission of electrons ...
Double differential cross sections for liquid water ionization by fast electron impact
(Springer, 2017-05)
In this work we study theoretically the single ionization of liquid water by impact of energetic electrons. A realistic description of the wavefunction for an isolated water molecule in the liquid phase is made by means ...
