摘要: Detection of elastically scattered recoils instead 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 excellent quality large area ionization detectors with particle position resolution are shown be very suited combination fully utilize potential ERDA method. Using 170 MeV I or 200 Au sensitivity below 1014atoms/cm2 depth 10 nm were obtained 7.5 msr detector solid angle. The enables correction kinematic energy shifts and, in addition, observation blocking patterns from single crystalline materials.
