Auger electron is a term that is widely used in the field of physics and chemistry. It is a type of electron that is emitted from an atom when it undergoes a relaxation process. Auger electrons are important in many scientific applications, including surface analysis, material science, and nuclear physics. In this article, we will define and explore the meaning of Auger electron, its origin, associations, synonyms, antonyms, and example sentences.
Definitions
An Auger electron is an electron that is emitted from an atom or molecule after the absorption of energy. It is a type of secondary electron that is produced when an atom is ionized. Auger electrons are named after the French physicist Pierre Auger, who discovered the phenomenon in 1925.
Origin
The Auger effect was first observed by Pierre Auger in 1925 while he was studying the photoelectric effect. He noticed that when X-rays were absorbed by a metal, the energy was not always transferred to an electron that was ejected from the atom. Instead, the energy was sometimes transferred to another electron that was already in the atom, causing it to be ejected. This process was later named the Auger effect, and the emitted electron was called an Auger electron.
Meaning in different dictionaries
- According to Merriam-Webster, an Auger electron is “an electron that is emitted from an atom as a result of the Auger effect.”
- Oxford Languages defines an Auger electron as “an electron that is emitted from an atom when it undergoes a relaxation process.”
- The Cambridge Dictionary defines an Auger electron as “an electron that is emitted from an atom after it has absorbed energy.”
Associations
Auger electrons are associated with many scientific applications, including surface analysis, material science, and nuclear physics. They are used to study the electronic structure of materials and to identify the composition of surfaces. Auger electrons are also used in medical imaging and cancer treatment.
Synonyms
- Secondary electron.
- Ejected electron.
- Auger electron spectroscopy (AES).
Antonyms
- Primary electron.
- Incident electron.
The same root words
The word Auger comes from the Old French word augier, which means “to bore.” The Auger effect is named after Pierre Auger, the physicist who discovered it.
