Surface sensitive PIXE

The application of nuclear methods to studies of ceramic surfaces and interfaces is a well-developed methodology, although not as yet applied extensively to mineral surfaces. Relevant applications of RBS, PIXE, NRA, ERDA and high-resolution a-spectroscopy have been described in the review by Matzke [9.1]. Analyses by RBS, used in the channeling mode, and NRA have revealed structural defects in U Ov-y RBS is sensitive mainly to the metal atom sublattice. whereas NRA can be used selectively to study the nonmeial sublattice. It was shown that the U sublattice is nearly identical to that of UO2, whereas significant cluster formation occurs in the O sublattice these observations have implications for surface sites in the material. Investigations of surface reactions (e.g., leaching and dis.soIution) of titanates and UO2 by nuclear techniques have... [Pg.576]
