摘要

Abstract

We present the electronic structure and electron energy loss spectroscopy (EELS) for uranium, niobium and U,3,Nb in which uranium is substituted by niobium. Comparing the electronic structures and optical properties for uranium, niobium and U,3,Nb, we found that when niobium atom replaces uranium atom in the center lattice, density of state (DOS) of U,3,Nb shifts downward to low energy. Niobium affects DOS for ,f, and ,d, electrons more than that for ,p, and ,s, electrons. U,3,Nb is similar to uranium for the electronic energy loss spectra.
