Abstracts

EN

Photoemission spectra for the Cd(0001) surface in the Γ̅-M̅ azimuth were calculated using a multiple scattering method. The emission angle of the photoelectrons θ was kept constant and equal to 35°. The photon energy was varied from 20 eV to 27 eV. The self-consistent potential used in the calculations was generated by the scalar-relativistic LMTO method. A modified image potential for the surface barrier potential was applied. The photoemission spectra show a strong surface state peak at an energy of about 1 eV below the Fermi level.
