Abstract
A method to study the density-of-states function by means of a CMA spectrometer is proposed which takes into account the diffraction effects of the inelastic-scattering electrons. The underlying principles of the method as well as its experimental verification for the case of the (001) single face of a tungsten crystal are presented. The experimental results are shown in the form of a set of the EELS spectra measured as a function of the primary electron energy, E p, which was varied in the range from 30–100 eV. Taking into account the diffraction effects the energy loss peaks have been correlated with inter- and intra-band excitation energies based on the theoretical results published by N.E. Christensen and B. Feuerbacher [Phys. Rev. B 10 (1974) 2349].
