In the analytical technique of photoelectron spectroscopy (PES), a sample is ionized using high-energy radiation, and the kinetic energies of the ejected electrons (called photoelectrons) are measured. From this, we can determine the binding or ionization energy of each electron in the atom or molecule. PES stands for photoelectron spectroscopy, which in the case of our lab is performed on negative ions. Here's how negative ion photoelectron spectroscopy works: a laser is used to detach the extra electron from a mass-selected beam of negative ions, and the kinetic energies of the electrons are measured in a hemispherical energy analyzer.
X-ray photoelectron spectroscopy (XPS), also known as electron spectroscopy for chemical analysis (ESCA), is a technique for analyzing a material’s surface chemistry.

In combination with theoretical calculations, it provides a powerful insight into the detailed electronic structure of molecules. Photoelectron Spectroscopy Photoelectron spectroscopy (PES) is based on the photoelectric effect, the fact that matter irradiated by photons of sufficiently high energy emits electrons. Information about the sample is determined from the intensity, the angular distribution, and the spin of the emitted electrons.

This page critically 24 Sep 2020 X-ray photoelectron spectroscopy (XPS) has become one of the most widely used surface analysis techniques, and XPS instrumentation has X-Ray and UV Photoelectron Spectroscopy. In photoemission techniques, we use either X-rays or ultraviolet photons to bombard the surface of a sample. Photoemission at high kinetic energies excited with hard x-ray photons (HAXPES or HIKE) is a truly bulk sensitive spectroscopy.
