Electron Energy Loss Spectra and Optical Constants for the First Transition Series from 2 to 120 eV

Energy loss spectra in the first series transition metals (Ti, V, Cr, Mn, Fe, Co, Ni) have been performed by transmission of 35 keV electrons through thin films (200 to 400 Å) in the spectral range 2 to 120 eV. Experimental data processing enables to distinguish between single scattering volume losses and surface losses. Characteristic functions, such as the energy loss function, the complex dielectric constant, and the optical absorption coefficient are computed and compared with results obtained by different methods.
