Effect of plasmon dispersion in inelastic scattering of fast electrons with deep hole excitation in fietals

We investigate the effect of plasmon dispersion in the inelastic scattering of fast electrons with excitation of a deep hole in metals. It is shown that allowance for plasmon dispersion leads to the replacement of singular satellite peaks in the energy-transfer spectrum by finite maxima. With the growth of the energy transfer the differential cross section of the processes falls off according to an exponential law.
