Electron spectroscopy

Japanese: 電子分光 - でんしぶんこう（英語表記）electron spectroscopy

A general term for methods of irradiating a material with light (X-rays, ultraviolet light), electrons, ions, excited molecules, etc., and measuring the kinetic energy distribution of electrons emitted from the material (this is called electron spectroscopy). Methods are classified according to the difference in the irradiation source and the electron emission process. Methods that use light irradiation are called photoelectron spectroscopy (abbreviated as PES). Of these, those that use X-rays are called X-ray photoelectron spectroscopy (abbreviated as XPS), and those that use ultraviolet light are called ultraviolet photoelectron spectroscopy (abbreviated as UPS).

物質に光(X線，紫外線)，電子，イオン，励起分子などをあて，物質から放出される電子の運動エネルギー分布を測定する(これを電子を分光するという)方法の総称。照射源と電子放出過程の相違により分類される。光照射による方法を光電子分光photoelectron spectroscopy(略称PES)という。そのうちX線によるものをX線光電子分光X‐ray photoelectron spectroscopy(略称XPS)，紫外線によるものを紫外光電子分光ultraviolet photoelectron spectroscopy(略称UPS)と呼ぶ。
