摘要
Results of calculations using time-dependent density functional theory and an analytic solution of the mean-field Newns-Anderson model are compared for the spectrum of electronic excitations generated by the adsorption of H-atoms on the Al(111) surface. It is shown that the main features of the spectra as a function of the incident energy of the H atoms are similar, but some details are not in quantitative agreement. (c) 2008 Elsevier B.V.
