• The angular distribution (AD) of scattered electrons produced by medium energyincident electrons (E.= 50 - 300 eV) from polycrystalline Ti, Fe, Ni, Cu and Au wereobtained by the angle-resolved medium energy electron spectrometer. The AD of theenergy loss peaks are similar figures to AD of the elastically reflected electron peaks.Therefore, the exchanged electrons produced by the knock-on collision between theincident electrons and those of metals without momentum transfer are observed asthe energy loss spectra (ELS). This interpretation differs from the inconsequent infer-pretation by the dielectric theory or the interband transition. The information depthand penetration length are obtained from AD of the Auger electron peaks. The contribution of the surface to spectra is 3% at the maximum for f.=50 eV. The truesecondary peaks representing the secondary electron emission spectroscopy (SES) arecaused by the emissions of the energetic electrons (k7'. ! 4 eV), and SES is the inversion of ELS. The established fundamental view is that the medium energy electronspectra represent the total bulk density of states.
