The critical examination of the spectral sensitivity to the Cu(001)-O surface provides evidence for that the VLEED are highly more sensitive to the bonding geometry than individual atomic-shift. The shapes of the fine-structure features are dominated by the elastic potential that determines thephase change of the diffracted beams. The inelastic potential influences on the absolute intensity other than the shape of the I-V curve. It is justified that the inelastic damping is predominated by the outermost layer. Therefore the VLEED is such a technique that it is able to reveal nondestructive information from the overlayer integrating the bond forming and the behaviour of surface electrons.
Keywords:LEED, Chemisorption
