Electron ionization is a technique used in mass spectrometry where high-energy electrons are used to ionize gas-phase atoms or molecules, resulting in the formation of positively charged ions. This method is widely used for its ability to produce reproducible mass spectra, although it can cause extensive fragmentation of the analyte.

High-energy electrons are electrons that possess significantly greater kinetic energy than typical electrons, often as a result of acceleration by electric fields or interactions with electromagnetic waves. These electrons play a crucial role in various fields, including particle physics, radiation therapy, and materials science, due to their ability to penetrate materials and induce secondary processes.
