Contribution to the Plasmon Satellite in Soft X-Ray Emission Spectra of Light Metals

Abstract

The plasmon satellite in the soft X-ray emission spectra of light metals is discussed using the method of Bohm and Pines. The transition probabilities for both K- and L-emission cases are obtained generally as the functions of plasma frequency, cut off wave number, Fermi energy and gap energy between the bottom of valence band and bound level. The numerical calculation is given for the case of Na L-emission. The results are compared with that given by Brouers; in the case of Na L-emission, it is shown that the spectrum rises more rapidly from the higher energy edge to the peak which is pointed.
