摘要：

Detection of elastically scattered recoils instead of projectiles offers the possibility to unambiguously identify sample components and is still a quantitative method for materials analysis. Large electrostatic accelerators delivering high energetic heavy ion beams of excellent quality and large area ionization detectors with particle and position resolution are shown to be a very suited combination to fully utilize the potential of the ERDA method. Using 170 MeV I or 200 MeV Au beams a sensitivity below 10(14) atoms/cm2 and depth resolution below 10 nm were obtained with 7.5 msr detector solid angle. The position resolution enables the correction of kinematic energy shifts and, in addition, the observation of blocking patterns from single crystalline materials.
