Outline of Final Research Achievements

Measurements of XAFS have been performed for electro- and electroless-deposition films formed in combination with an UV irradiation treatment on non-conductive substrates. Although XANES spectra of the Ag L3 edge (3.35 keV) represented no significant difference, the results suggested the existence of an oxidation layer at an outermost surface. An in-situ XAFS system equipped with a sample heating holder has been developed. The system is applicable for both of a conversion electron yield method and a partial fluorescence yield method using an X-ray energy below 4 keV in He gas.
