Energetic D+ and He+ impinging on solid beryllium: Observation of physical and chemically assisted atomic and molecular ion sputtering Open
Our Surface-Time-Of-Flight (SurfTOF) tandem mass spectrometer apparatus has been employed in a comparative investigation of ion sputtering induced by mono-energetic D+ and He+ ion beams impinging on a Be surface at 700 K with impact energi…

Formation of HCN<sup>+</sup> in collisions of N<sup>+</sup> and N<sub>2</sub><sup>+</sup> with a self-assembled propanethiol surface on gold Open
Collisions of N+ and N2+ with C3 hydrocarbons, represented by a self assembled monolayer of propanethiol on a polycrystalline gold surface, were investigated by experiments over the incident energy range between 5 eV and 100 eV.

Mixed cationic clusters of nitrogen and hydrogen Open
The addition of small impurities, such as a single proton charge carrier, in noble gas clusters has recently been shown to have considerable effects on their geometries and stabilities. Here, we report on a mass spectrometric study of cati…

Formation of beryllium-hydrogen ions in chemical sputtering from 20 to 420eV Open
The formation of BeD+ in collisions of deuterium molecular ions with a beryllium surface at hyperthermal energies is investigated, using a purpose-built tandem mass spectrometer setup, “SurfTOF”. In the manifold of products, hydrogen-conta…
