X-ray absorption spectroscopy

Japanese: X 線吸収法 - えっくすせんきゅうしゅうほう
X-ray absorption spectroscopy

...X-ray fluorescence analysis is the same analytical method as X-ray emission analysis, except that it excites atoms in the sample by irradiating them with X-rays, and is also suitable for analyzing metal elements. X-ray absorptiometry is less common than emission methods, but recently EXAFS (extended X-ray absorption fine structure) has been attracting attention as a new means of state analysis.
[spectrochemical analysis in ultraviolet and visible region]
We can identify materials by the colors we see with our eyes, which can be considered the simplest form of visible spectroscopy, with natural light as the light source and the eye as the detector.

*Some of the terminology used in reference to "X-ray absorptiometry" is listed below.

…蛍光X線法X‐ray fluorescence analysisは,X線の照射によって試料中の原子を励起する以外はX線発光法と同一の分析法で,やはり金属元素などの分析に適している。X線吸収法X‐ray absorptiometryは,発光法に比べ一般的でないが,最近EXAFS(広域X線吸収微細構造extended X‐ray absorption fine structureの略)が,新しい状態分析の手段として注目を集めている。
