Definition: Electron capture is a type of radioactive decay where the nucleus of an atom absorbs a K or L shell electron and converts a proton into a neutron. This process reduces the atomic number by 1 and emits gamma radiation and a neutrino.
In a photoelectron spectroscopy experiment any electron can be ionized when the atom is. excited. Like the first ionization only one electron is removed from the atom, however in. the PES experiment it can be any electron, not just the electron that requires the least. amount of energy.
