X-Ray-induced low-energy electron emission from solids (one-dimensional theoretical model)

Abstract

Abstract The effect of the solid surface on the X-ray induced low-energy electron emission is analysed, using the formalism of the general scattering theory, by means of an approach, called by us the ‘diagonalisation method’. Explicit analytical expressions and numerical results, obtained in the one-dimensional approximation, show great sensitivity of the shape of electron emission spectra near the threshold to the surface potential barrier height and to the presence of the amorphous ‘transition’ layer.
