  The density of electronic states for bulk metals Au and Pd, their surfaces in
the form of polycrystalline surface layers of nanometer thickness is
investigated. The calculations were performed using density functional theory
with pseudopotential in full relativistic approximation. Approximations have
been found that provide calculations the density of electronic states of noble
metal surfaces that describe the experimentally observed features of XPS
spectra of the valence band of these metals.
