X-Ray Photoelectron Spectroscopy (XPS)-2
public.wsu.eduPhotoelectron lines have a. Lorenzian shape. corresponding to the lifetime of the core hole that is created. Gaussian or Gaussian Lorentzian shape GL(30) curves are often used for curve fitting purposes. Deconvolution of the XPS Mo samples reveals the existence of several Mo species (Mo. 0, Mo4+, Mo6+ but others could also be detected: Mo3+ and ...
Gamma Ray Spectroscopy - University of Michigan
www-personal.umich.eduThe photoelectric absorption interaction is the ideal interaction for gamma-ray spectroscopy. The photoelectron carries away most of the gamma-ray energy and then an X-ray or Auger electron carries away the remaining kinetic energy. Assuming an ideal detector, the sum of these energies will equal the energy of the original gamma-ray.
