Nanoclusters of gold are prepared at (001) surface of GaP crystals by a chemical method which does not require heating the sample. Characterization of obtained nanostructures Au/GaP was performed and their plasmons are investigated by reflection anisotropy spectroscopy technique. It is shown that the spectral feature at energy about 2 eV belongs to weakly anisotropic Au nanoclusters elongated presumably in crystallographic [110] direction at GaP(001) surface. Keywords: gold clusters, gallium phosphide, polarization spectroscopy, anisotropic plasmons.
