Abstract

Based on modeling the optical-conductivity spectrum estimated from the data of optical experiments, the electronic structure of nonoxidized and oxidized surfaces of liquid, amorphous, and polycrystalline Al-8 at % Ce alloy is studied. The conduction band of the alloy in the liquid and amorphous states is found to be split. In the polycrystalline state, there is no splitting. The heat of adsorption of oxygen on the alloy surface is calculated for amorphous and polycrystalline alloy states.
