Nuclear microprobe local hydrogen measurements in HTPC

Elastic Recoil Detection Analysis (ERDA) combined with Rutherford back-scattering (RBS) was first exploited for perovskites containing very low hydrogen contents. A less common method has been developed for thin samples which utilized 1H(p,p)1H forward scattering with coincidence detection (ERCS). From the broad compositional and structural range of perovskites, we have limited our efforts to SrCe0.9Y0.1O3−δ and Sr3Ca1+xNb1.82O9−δ, compositions which represent simple and complex perovskite structures, respectively.
