Electron ionization (EI, formerly known as electron impact ionization and electron bombardment ionization) is an ionization method in which energetic...

solution for the ionization rate is possible. Tunnel ionization is ionization due to quantum tunneling. In classical ionization, an electron must have enough...

stripped of a single electron, and e− is the removed electron. Ionization energy is positive for neutral atoms, meaning that the ionization is an endothermic...

by the electron beam ion trap. Electron capture ionization (ECI) is the ionization of a gas phase atom or molecule by attachment of an electron to create...

Electron capture ionization is the ionization of a gas phase atom or molecule by attachment of an electron to create an ion of the form A − {\displaystyle...

chemistry. Reagent gas molecules (often methane or ammonia) are ionized by electron ionization to form reagent ions, which subsequently react with analyte...

manufacturers. The "hard ionization" process of electron ionization can be softened by the cooling of the molecules before their ionization, resulting in mass...

electron in its lowest energy state from an atom or molecule of a gas with less net electric charge is called the ionization potential, or ionization...

is commonly used for the identification of organic compounds from electron ionization mass spectrometry. Organic chemists obtain mass spectra of chemical...

the Auger electron corresponds to the difference between the energy of the initial electronic transition into the vacancy and the ionization energy for...
