摘要：

The electronic structure of the lanthanum oxide surface with an adsorbed As atom has been studied by the X-alpha method. Analysis of the occupied electronic density of states and contour maps of the valence-electronic charge density for the bulk and adsorbed surface clusters shows pronounced differences connected with Asp- and La s + La d-state hybridization. The influence of these factors on absorption-spectra features is discussed. The surface reduction effects are considered.
