Resource center 'Physical methods of surface investigation' (PMSI) is assigned for scientific ultrahigh vacuum investigations devoted to study of processes of formation of surface nanostructures and composite materials, analysis of their features of electron energy and spin structure by methods of X-ray, Auger and Ultraviolet Photoelectron Spectroscopy with angular and spin resolution and also of the local atomic structure and morphology by ultrahigh vacuum scanning tunneling and atomic force microscopies.
