Fe K-edge

The Fe K-edge refers to a specific energy level at which iron atoms absorb X-ray radiation. When X-rays with this energy hit a material containing iron, the iron atoms absorb the X-rays, causing core electrons to jump to higher energy levels or be ejected. This absorption produces a distinctive feature in the X-ray spectra called the K-edge, which reveals information about the iron's chemical state and local environment. In scientific studies, analyzing the Fe K-edge helps researchers understand how iron is bonded and behaves within different materials or biological systems.
