摘要：

The optical constants for Ti, V, Fe, Co, and Ni determined by reflection electron energy loss spectroscopy (REELS) are reported. The optical constants were calculated from the experimental REELS data using an empirical data treatment method previously reported [Appl. Surf. Sci. 44 (1990) 279, 293]. The purpose of this study is to further evaluate the data treatment method on electronically more complex metals. The REELS experimental spectra, taken with primary beam energies of 1500 and 200 eV, are discussed along with the resulting optical constants. These results are compared to values reported in the literature. From this comparison, it is shown that the method is effective in approximating the real (ε{lunate}1) and imaginary (ε{lunate}2) parts of the dielectric constant for Ti, V, Fe, Co, and Ni. © 1990.
