We present results of the analysis of K-edge X-ray-absorption spectra of crystalline, amorphous, and supercooled Ge. The EXAFS spectra are analyzed in k space by comparison with theoretical signals calculated including the total multiple-scattering (MS) contributions related to pairs and triplets of Ge atoms. MS signals of triangles are unambiguously identified in the various systems investigated.

Abstract
We present results of the analysis of K-edge X-ray-absorption spectra of crystalline, amorphous, and supercooled Ge. The EXAFS spectra are analyzed in k space by comparison with theoretical signals calculated including the total multiple-scattering (MS) contributions related to pairs and triplets of Ge atoms. MS signals of triangles are unambiguously identified in the various systems investigated.File in questo prodotto:
