X-ray absorption spectrum

Japanese: X 線吸収スペクトル - えっくすきゅうしゅうすぺくとる
X-ray absorption spectrum

…When continuous X-rays are transmitted through a substance, the spectrum of the transmitted X-rays is either missing or weakened due to the absorption of wavelengths specific to the elements that make up the substance. This is called the X-ray absorption spectrum, and is the absorption edge when the specific wavelength is the absorption coefficient. In developed countries, including Japan, the use of electron synchrotrons is becoming more common as a method of obtaining continuous X-rays. …

Japanese:

…連続X線を物質に透過させると,透過X線のスペクトルは,その物質を構成する元素特有の波長部分が吸収されて,その部分が欠けるかあるいは弱められたものとなる。これをX線吸収スペクトルといい,その特有の波長が吸収係数の場合の吸収端である。 連続X線を得る方法として,日本を含む先進国では電子シンクロトロンの利用が進んでいる。…
