Abstract
The stopping cross section data measured by foil transmission often show an energy dependence different from that of RBS measurements. This cannot be due to problems connected with foil thickness-determination. Therefore, we investigate in this contribution, how the energy loss data in these types of measurements are influenced by the different projectile paths due to impact-parameter selection, plural and multiple scattering, by target properties such as bulk and surface impurities, texture and desity differences and by the use of different energy analyzers. Experiments have been performed which prove the reliability of our target preparation, stopping cross section measurements and data evaluation with respect to these influences.
