The energy loss function Im (−1/ϵ(Δ E )) of polycrystalline Mo films is determined by electron energy loss experiments in transmission with 56 keV electrons. By means of Kramers‐Kronig analysis the complex dielectric function ϵ = ϵ 1 + i ϵ 2 and the reflectivity R (Δ E ) are calculated in the energy range from 1.5 to 38 eV. The results are compared with those obtained from optical reflectance data.
