The ionization of an atom or molecule by electrons that are typically accelerated to energies between 50 and 150 eV. Usually 70 eV electrons are used to produce positive ions. The term '[[electron impact]]' is not recommended.

Gold Book Entry

This is the term used to describe ionization of any species by electrons. The process may, for example, be written:

for atoms or molecules:

M + e --> M+. + 2e

for radicals:

M. + e --> M+ + 2e

The term 'electron impact' should not be used.
