La structure locale autour de certains métaux de transition (Cr-Fe-Co-Ni) présents dans des verres silicatés ou boratés est étudiée à partir des résultats de la spectrométrie d'absorption X. La complémentarité des informations qui peuvent être obtenues à partir des oscillations "EXAFS" (distance des atomes voisins) et de la structure du seuil (symétrie, état chimique) est mise en évidence.Absorption X-ray spectroscopy is used to study the local structure around transition elements (Cr-Fe-Co-Ni) in silicate and borate glasses. The complementarity of EXAFS, giving the neighbour distances, and of the near edge structure giving informations about symmetry and chemical state is emphasized
