FEFF

FEFF is a computational software used by scientists to study how atoms and materials absorb X-rays. It helps analyze the local atomic environment around a specific element by simulating how X-ray energy interacts with the material. This information is crucial for understanding the structure and properties of materials at the atomic level, useful in fields like material science, chemistry, and physics. Essentially, FEFF provides detailed insights into the arrangement and behavior of atoms in a substance based on X-ray absorption data.
