The difference in deuterium content after drying at lower temperatures presumably reflects weakly sorbed D, while that surviving at the higher temperatures probably represents deutroxylated species. Elastic recoil detection P Figure 1. Elastic Recoil Detection Analysis (ERDA), also referred to as forward recoil scattering (or, contextually, spectrometry), is an Ion Beam Analysis technique in materials science to obtain elemental concentration depth profiles in thin films. This technique employs a high energy heavy ion beam to eject nuclei from the target and uses a time of flight and energy dispersive (ToF-E) detector telescope to detect these nuclei. Studies of the hydrogen content and profiles of surfaces can be difficult in some cases, due to the pickup of atmospheric moisture by the sample causing an unwanted hydrogenous background. So, in RBS we are detecting the energy loss of the primary particle. Academic & Science » Electronics. ERDA is a complementary method to RBS. A thin filter, typically mylar, is placed in front of the detector to stop and block-out the elastically scattered incident ion beam, which would otherwise overload and quickly destroy the detector. The sample to be analyzed is irradiated with an ion beam (e.g. With these very low leach rates, the ambient hydrogenous background can easily mask out surface alteration effects. It is used principally as a method for measuring hydrogen in thin layers, and in the near-surface region of materials.
