photoelectron spectroscopy electron-induced photoelectron spectroscopy Spectroscopy where the sample is bombarded with electrons causing ionisation and the emission of photoelectrons, the energies of which are measured. The energy of the incident electrons is usually greater than the ionisation energy of the sample and the photoelectrons are emitted with the excess in the form of kinetic energy. electron-induced PES 2009-08-24T02:32:13Z CHMO:0002295 https://orcid.org/0000-0001-5985-7429
