摘要:
X-Ray absorption and X-ray photoelectron spectroscopic measurements of specular surfaces using grazing incidence soft X-rays carried out by the present authors are summarized. The merits of using a sample current induced by totally reflected X-rays are discussed. The probing depth of the sample current has been found to be restricted to within a very shallow surface. The application of the sample current X-ray absorption experiment to the depth profile analysis of flyash powders is described. Very clear X-ray photoelectron spectra excited by totally reflected X-rays are for the first time reported.
