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

The effect of the solid surface on the X-ray induced low-energy electron em ission is analysed, using the formalism of the general scattering theory, b y means of an approach, called by us the 'diagonalisation method. Explicit analytical expressions and numerical results, obtained in the one-dimension al approximation, show great sensitivity of the shape of electron emission spectra near the threshold to the surface potential barrier height and to t he presence of the amorphous 'transition' layer.
