Photoelectron spectroscopy, usually abbreviated PES, is a lab technique that involves shooting an intense beam of radiation at a sample of an element and measuring the energy of the electrons that Photoelectron spectroscopy (PES) utilizes photo-ionization and analysis of the kinetic energy distribution of the emitted photoelectrons to study the composition and electronic state of the surface region of a sample. X-ray Photoelectron Spectroscopy (XPS) uses soft x-rays (with a photon energy of 200-2000 eV) to examine electrons in core-levels.

Photoelectron spectroscopy - a single photon in / electron out process Photoelectron spectroscopy (PES) is a technique used for determining the ionization potentials of molecules.
In this technique, the electrons are ejected from a packet of mass-selected anions ( A - ) by intersecting it with the harmonics of a Nd:YAG laser (1064 nm, 532nm, or 355 nm) or by the output of a mid X-ray photoelectron spectroscopy X-ray photoelectron spectroscopy (XPS) is a quantitative technique for measuring the elemental composition of the surface of a material, and it also determines the binding states of the elements. XPS normally probes to a depth of 10 nm.
