...When electrons are bombarded against a material, electrons can be emitted either directly or indirectly (Auger effect). Spectroscopy of electrons by the former process is called electron impact spectroscopy (EIS), and spectroscopy of electrons by the latter process is called Auger electron spectroscopy (AES). In EIS, the focus is on the emitted electrons (secondary electrons) that have lower energy than the electrons that were struck (primary electrons), so the term electron energy loss spectroscopy (EELS) is also used. ... *Some of the terminology that refers to "electron impact spectroscopy" is listed below.

…物質に電子をあてるときは,直接電子を放出する場合と間接的な過程(オージェ効果)で電子を放出する場合がある。前者の過程による電子の分光を電子衝撃分光electron impact spectroscopy(略称EIS),後者の過程による電子の分光をオージェ電子分光Auger electron spectroscopy(略称AES)という。EISではあてた電子(一次電子)よりエネルギーの低い放出電子(二次電子)に着目するので,電子エネルギー損失分光electron energy loss spectroscopy(略称EELS)という名称も使われる。… ※「electron impact spectroscopy」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
