### Abstract

Plasmon-loss spectra of clean polycrystalline molybdenum surfaces have been determined in the primary energy range E_{p} = 50-3000 eV. Spectra a distributions (nonderivative mode). A simplified model is described for evaluating plasmon-loss spectra using elastic-peak electron spectroscopy, as de of elastically reflected electrons is determined by integrating the N(E) spectrum of secondary and backscattered electrons. The ratio of the ar (23-24 eV) to that of the elastic peak is Pλ, the product of the probability for creating a volume plasmon loss and the inelastic mean free pat second plasmon-loss peak is (Pλ)^{2}. Evaluation of our experimental plasmon-loss spectra gives Pλ = 0.4-0.5 for E_{p} > 500 eV. Th constitutes ∼50% of all losses determining the IMFP, interband loss processes being important in the remainder. For the low energy range, E_{p} found. For E_{p} <100 eV, no volume plasmon-loss peak could be detected in our N(E) spectra. The simplified model proves to be valid fo plasmon-loss peak (11-12 eV), i.e., such that N_{pls}/N_{e} {reversed tilde equals} 10^{-2}. Some results are presented concerning surface plasmon losses as molybdenum surface.
