Abstract

X-ray photoelectron spectroscopy data are analyzed by solving the problem of the photoemission-current density function using the invariant immersion method. X-ray photoelectron spectra in a wide energy loss range are described on the basis of exact solution of the problem of elastic photoelectron scattering in solids using the discrete ordinate technique. The X-ray photoelectron spectrum is recorded in the form of a series of inelastic scattering orders. Comparison of the results of the exact solution with the data of transport and small-angle approximations reveals significant errors in the approximate solutions in X-ray photoelectron spectroscopy. The spectra calculated using different approximations are presented and compared with the experiment. The errors of the traditional background subtraction procedures are considered.
