near edge X-ray absorption fine structure

initialism: NEXAFS
https://doi.org/10.1351/goldbook.08738
Measurement method of X-ray absorption analysis similar to X-ray absorption near edge structure, but usually reserved for soft X-rays with photon energy less than \(\pu{1 keV}\).
Note:
NEXAFS is generally used in surface and molecular science.
