Abstract
Spectra from X-ray photoelectron spectroscopy (XPS) measured over a wide range of energy loss are analyzed. The analytic description of XPS spectra over a wide range of energy loss is based on a precise solution to the problem of elastic scattering of photoelectrons in solids. A precise numerical solution is obtained by means of discrete ordinates method. The XPS spectrum is represented as a series by quantity of inelastic scattering. The inconsistency of ignoring multiple elastic processes by using straight line approximations (SLAs) in describing XPS energy spectra is demonstrated.
