Abstract
The combination of PIXE and RBS measurements enables the deconvolution of the interference between the Cd-L- and the K-K(alpha)-line for the quantitative analysis of Cd-concentration in the ppm region. An evalu ation of the experimental data using the results of these measurements is given. The scattering cross sections for protons on nitrogen, oxyg en, silicon and potassium were determined in the energy range between 1.0 and 1.8 MeV by means of calibration standards formed by ion implan tation in order to reduce the experimental error of the RBS investigat ion. A comparison with alternative methods confirms the accuracy and s ensitivity of our measurements.
