The parameters of RBS analysis that is under influence of experimental conditions has been investigated by the experimental methods and the theoretical calculations, i.e. the energy resolution, the accessible depth and the depth resolution. The results of theoretical calculations for the depth resolution parameter at varying incident energies and target tilting angles was verified by backscattering experiments on Au sample and they have found to be in good agreement with experimental results. The optimum analysis conditions over a wide range of RBS applications can be found by extensions of theoretical calculations. All the experiments was conducted in the RBS system at HUS 5SDH-2 Tandem accelerator.
