Insights from the zero-angular-momentum wave in single and double ionization of He by fast electrons
(American Physical Society, 2014-01)
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 ...

Electron-impact multiple ionization of Ne, Ar, Kr and Xe
(Iop Publishing, 2014-05)
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 ...
Two center and Coulomb effects in near-threshold ionization of H+ 2 by short laser pulses
(Taylor & Francis Ltd, 2009-01)
We investigate the influence of the Coulomb potential as well as the two center contribution in the angle-resolved photoelectron spectrum, resulting from the single ionization of H[image omitted] molecules by short laser ...
Energy Threshold in multiple ionization by electron or positron impact
(IOP Publishing, 2015-04)
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 ...

Influence of inner-shell electron removal on the multiple ionization of Kr and Xe by protons
(Iop Publishing, 2014-01)
The multiple ionization of Kr and Xe by protons has been analysed in detail within the independent particle model. The dependence of the multiple ionization cross sections on the values of the ionization probabilities ...
