Impact of the experimental approach on the observed electronic energy loss for light keV ions in thin self-supporting films
Barbara Bruckner, Philipp M. Wolf, Peter Bauer +1
Energy spectra of backscattered and transmitted ions with primary energies of 50 keV and 100 keV interacting with self-supporting foils were recorded with a Time-of-Flight Medium-E…
Electronic excitation of transition metal nitrides by light ions with keV energies
Barbara Bruckner, Marcus Hans, Tomas Nyberg +3
We investigated the specific electronic energy deposition by protons and He ions with keV energies in different transition metal nitrides of technological interest. Data were obtai…
On the influence of uncertainties in scattering potentials on quantitative analysis using keV ions
Barbara Bruckner, Tomas Strapko, Mauricio A. Sortica +2
Experimental spectra from medium energy ion scattering were compared to Monte-Carlo simulations (employing the TRBS code) to obtain information on the scattering potential. The imp…
Neutralization of slow helium ions scattered from single crystalline aluminum and tantalum surfaces and their oxides
Barbara Bruckner, Peter Bauer, Daniel Primetzhofer
We investigated the impact of surface oxygen on the ion yield for He ions scattered from different single crystalline surfaces in low-energy ion scattering. Initially clean Al(…
Electronic Stopping of Slow Protons in Transition and Rare Earth Metals: Breakdown of the Free Electron Gas Concept
D. Roth, B. Bruckner, M. V. Moro +8
The electronic stopping cross sections (SCS) of Ta and Gd for slow protons have been investigated experimentally. The data are compared to the results for Pt and Au to learn how el…
