Abstract
The circular dichroism of angle-resolved photoelectron spectra was inv estigated for core-levels from clean and hydrogen exposed GaAs (111) s urfaces. It was found that the circular dichroism of Ga-3d and As-3d p hotoelectrons shows clear dependence on the emission angle of the phot oelectrons and the sample surface. It is proposed that the experimenta l results may be interpreted primarily in terms of the interference of photoelectrons affected by the anisotropic field in the surface layer of GaAs (111).
