The influence of surface defects on the low energy scattering of Ar ions from a Cu(111) surface
(Elsevier Science, 2019-12)
Low-energy ion scattering (LEIS) is distinguished by its acute surface sensitivity. Depending on the projectile/target system under analysis and the incoming energy of the projectile, it can provide information on the ...
Effects of electron-hole excitations in ion-surface collisions
(Pergamon-elsevier Science LtdOxfordInglaterra, 2003)
The effect of the projectile intra-site Coulomb repulsion in the surface scattering of many-electron ions.
(Elsevier Science, 2003-11)
In this work a theoretical study of the collision of many-electron ions with a surface is performed. The case of largeangle collisions with respect to the surface and projectiles with an open shell is treated. Two important ...
Image potential state Influence on Charge Exchange in Li+ - Metal Surface Collisions
(American Chemical Society, 2014-04)
The energy dependence of the neutral fraction of ions scattered by metal surfaces is observed to be affected by the presence of energy gaps and surface states in their surface band structure. The effect is more dramatic ...
Theoretical study of the charge transfer and electron emission in the scattering of He+ by an AlF3 surface
(American Physical Society, 2017-08)
Experimental results of electron emission from surfaces of aluminum fluoride impacted by keV noble gas ions (He+, Ne+, Ar+) show a high-energy structure that increases in intensity with ion energy in the case of He+ and ...
Neutralization mechanisms in He+-Al surface collisions
(Elsevier Science, 2007-10)
From a quantum mechanical calculation where the populations of He ground and first excited states are properly taken into account, we can identify for the first time the neutralization to the He first excited state as an ...
Experimental and theoretical study of charge transfer in hydrogen ion scattering from a graphite surface
(Elsevier Science, 2007-12)
Ion scattering spectrometry (ISS) with time of flight (TOF) analysis is employed to measure the ion fraction of positively charged hydrogen (H+) projectiles scattered from a well characterized highly oriented pyrolitc ...
Electronic correlation effects on the neutralization of Ga+ scattered by a gold surface
(American Physical Society, 2017-08)
The monotonous increasing with temperature behavior of the neutralization of Ga+ scattered by a gold surface plus the nonmagnetic character of the ion induced to disregard the important electronic correlation effects. In ...
