Some experimental results of solid surface studies using synchrotron radiation are described. Experiments were carried out with the light monochromatized by a grazing incidence monochromator at the BL 8A the Photon Factory. As a result, photoemission spectroscopy with an energy resolution of 0.3 eV has been achieved. Using this method, oxidation process of Si (100) surface has been examined. The results of SEXAFS and XANES for various oxide compounds are also presented.
