Electron and energy transfer processes between an atom or molecule and a surface are
extremely important for many applications in physics and chemistry. Therefore a profound …

Abstract Low-Energy Ion Scattering (LEIS) spectrometry is extraordinarily sensitive and
specific to the outermost atomic layers of materials. It is a powerful tool for surface science …

We present experiments demonstrating trajectory-dependent electronic excitations at low
ion velocities, for which ions are expected to primarily interact with delocalized valence …

In recent energy loss measurements, band structure effects in electronic stopping have been
observed for materials with finite excitation thresholds, for example, noble metals such as Cu …

We explore under which conditions low-energy ion scattering experiments are capable of
obtaining reliable quantitative results in surface composition analysis. Additionally, we …

This work compares the charge exchange properties of a large set of pure elemental solid
targets by studying the neutralisation and reionisation in low-energy ion scattering (LEIS) …

Secondary electron emission is an important process that plays a significant role in several
plasma‐related applications. As measuring the secondary electron yield experimentally is …

Charge exchange between He ions and a Ni (111) surface containing oxygen was studied
by Low-Energy Ion Scattering, using 1.25 keV He+ as primary ions. The energy resolved …

When low-energy He ions are scattered from a Ge surface, the fraction of positive ions
exhibits characteristic oscillations as a function of ion energy. These oscillations are caused …

When slow ions incident on a surface are neutralized, the excess potential energy is passed
on to an electron inside the surface, leading to emission of secondary electrons. The …
