Abstract
In a round robin experiment a set of five polycrystalline, metallic sa mples is studied by low-energy ion scattering (LEIS) in five different laboratories, The energy range is 0.6-3.5 keV and He and Ne ions are used. Even though different experimental setups are used the evaluated elemental sensitivity factors agree within +/-20%. Reproducibility wi thin single laboratories is better than 10%. In an additional study ca rried out in three laboratories the surface composition of an alloy, C u55Pd45, was determined, using in situ calibration standards, These su rface composition measurements agreed within +/-3 at% demonstrating th at quantitative composition determination is possible using this proce dure.
