In a recent contribution our group proposed a perturbative approach to deal with the open problem of double ionization of helium by electron impact. The goal of this work is to delve into the physics of the scattering ...

This work describes the multiple ionization cross sections of rare gases by electron-impact. We pay special attention to the high energy region (0.1?10 keV) where the direct ionization is a minor contribution and the ...

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, ...

In this work, triply differential cross sections for single electron emission due to electron impact on the He-isoelectronic sequence are calculated by using a Born-C3 model. The influence of the nuclear charge on the ...

In this work, we consider the single ionization of Ar by 200 eV positron and electron impact. The quantum mechanical continuum distorted wave (CDW) model is used in the one-active electron approximation. Parametrizations ...

The ionization of the 3p orbital of argon by incident electrons and positrons is studied by means of the post version of the continuum distorted wave–eikonal initial-state model. Results are presented at both 200 and 500 ...

The energy threshold for the formation of highly charged ions is experimentallywell-known and measured. For single ionization, it is the binding energy of the outermost electrons. For multiple ionization, the ionization ...

The longitudinal recoil-ion momentum distributions of single ionization in collisions between fast heavy ions and atoms are analyzed by exploring the three-body kinematics and its relation to dynamic processes. It is found ...
