Abstract

Abstract: Hydrogen concentrations in thin self-supporting samples of polyphenylene sulfide (PPS) and muscovite have been determined by nuclear-elastic recoil detection analysis (ERDA) of transmission layout. The analysis procedure is based only on the database of stopping power and recoil cross section for material analysis, without using any reference sample of known H content. For the PPS sample, the determined value of ( 2.87 ± 0.26 ) × 10 22 H cm −3 is in good agreement with the calculated value of 3.01 × 10 22 H cm −3 . For the muscovite sample, the H concentration originating each from bound water and absorbed water is uniform over the entire thickness of the sample. The determined concentration ( 9.43 ± 0.75 ) × 10 21 H cm −3 of the muscovite agrees excellently with the value of 9.36 × 10 21 H cm −3 obtained from other quantitative analyses typically applied for minerals. The present results demonstrate the capability of accurate determination of H contents in materials and minerals by transmission ERDA.
