…Sometimes, an inner shell electron that is filled in the ground state of an atom is missing in the excited state due to some reason. When this happens, there are two processes by which an excited atom can return to the ground state. One is a process in which an electron in a shallow level falls into the vacant inner shell and emits the energy difference as X-rays, and the other is a process in which this energy difference is given to another electron, which is then released outside the atom. The latter phenomenon is called the Auger effect, and the electron that is released outside the atom due to this effect is called an Auger electron. … *Some of the terminology that mentions "Auger, P." is listed below.

…原子の基底状態では詰まっている内殻の電子が,励起状態において何らかの原因で抜けていることがある。このとき励起状態にある原子が再び基底状態に戻る過程には二つある。一つは浅い準位にある電子がこの内殻の空席に落ちるとともにエネルギー差分をX線として放出する過程であり,もう一つは,このエネルギー差分をさらに別の電子に与え,その電子を原子外に放出する過程である。後者の現象をオージェ効果と呼び,この効果で原子外に飛び出す電子をオージェ電子という。… ※「Auger,P.」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 |
