Preferred Name	Photoelectron Spectroscopy
Definitions	The study of the energy of electrons ejected from matter by the photoelectric effect, i.e., as a direct result of absorption of energy from electromagnetic radiation. As the energies of the electrons are characteristic of a specific element, the measurement of the energy of these electrons is a technique used to determine the chemical composition of surfaces. A form of photoelectron spectroscopy in which a sample is irradiated with a beam of ULTRAVIOLET RAYS and the energies of the resulting photoelectrons are analyzed. A form of photoelectron spectroscopy in which a sample is irradiated with a beam of monochromatic X-RAYS and the energies of the resulting photoelectrons are analyzed.
Synonyms	Spectroscopy, Photoelectron Spectroscopy, Xray Photoelectron Spectroscopy, Ultraviolet Photoelectron Photoelectron Spectroscopy, X-Ray Photoelectron Emission Spectroscopy Photoelectron Spectroscopy, Xray Ultra-Violet Photoelectron Spectroscopy Spectrometry, Photoelectron Photoelectron Spectrometry Spectroscopy, X-Ray Photoelectron X Ray Photoelectron Spectroscopy Photoelectron Spectroscopy, Ultraviolet Spectroscopy, Photoemission Emission Spectroscopy, Photoelectron Photoelectron Spectroscopy, Ultra-Violet Xray Photoelectron Spectroscopy Ultraviolet Photoelectron Spectroscopy X-Ray Photoelectron Spectroscopy Spectroscopy, Photoelectron Emission Emission Spectroscopies, Photoelectron Ultra Violet Photoelectron Spectroscopy Electron Spectroscopy for Chemical Analysis Photoemission Spectroscopy Spectroscopy, Ultra-Violet Photoelectron See more See less
