X-ray absorption fine structure (XAFS)

X-ray Absorption Fine Structure (XAFS) is a scientific technique used to study the local structure around specific atoms in a material. When X-rays are directed at a sample, some are absorbed by the atoms, which causes electrons to be ejected. By analyzing the energy and intensity of the absorbed X-rays, scientists can learn about the distances between atoms, their coordination, and the types of neighboring atoms. This information helps in understanding the material's properties and behavior at a microscopic level, making XAFS valuable in fields like chemistry, materials science, and environmental studies.
