The coatings were prepared by 3 . Abstract. The structure of amorphous alloys is an important field in materials research. The lack of an extensive regular structure in these amorphous materials, however, often limits the amount of unambiguous structural information which can be gained from conventional structural techniques such as x-ray, neutron, or electron diffractions. X-Ray Absorption Spectroscopy: EXAFS and XANES - A Versatile Tool to Study the Atomic and Electronic Structure of Materials E. E. Alp, S. M. Mini, and M. Ramanathan X-ray absorption spectroscopy (XAS) had been an essential tool to gather spectroscopic information about atomic energy level structure in the early decades of this century.
