Bimetal systems of Co/Au nanoparticles with core-shell structure were synthesized by the reduction – electrochemical replacement reaction in aqueous solutions. The core-shell structure is proved by spectroscopy in the visible area and by SAXS. Structure and properties of Co/Au nanoparticles can be successfully described by the «core-shell»model of spherical shape. Mass functions of particle size distribution were computed from the small-angle X-ray scattering curves in the approximation of
