【 摘 要 】

High energy resolution reflection electron energy loss spectroscopy (REELS) spectra measurements were performed for Ni. We present the differential excitation probabilities for electrons traveling in nickel extracted from the spectra by using the Werner's elimination-retrieved algorithm. The electronic structure and optical properties of nickel have been determined by using newly developed reverse Monte Carlo method.
