Electron Energy Loss

The electron energy loss fine structure (EELFS) method allows one to obtain information on atomic bond lengths from the surface to the bulk. But gaining more complete quantitative information for example on coordination numbers has not presently been realized. The possibility of obtaining normalized radial distribution functions (RDF's) is shown for EELFS spectra which may be used for deriving complete structural information on pure elements. RDF's were obtained by using the regularization algorithm (after A. N. Tikhonov). The method for obtaining the RDF's was applied to the experimental Fe M 2,3 EELFS spectrum.
