The invention of a new method to produce targets stable under prolonged intense irradiation conditions is very important for radiochemistry and nuclear chemistry. We suggest the method called “coupled reduction” which is based on the formation of the intermetallic compound layer. The novelty of our approach is to adapt this method for the preparation of high-power radioactive targets supplying the crucial properties for accelerator targets techniques. Nickel (Ni) was used as backing foil material, Palladium (Pd) and Europium (Eu) were used to get the intermetallic compound. For the preparation of such targets, at the first step, Pd as a diffusion layer was deposited onto the Ni backing foil by vacuum deposition. The target material Eu was electroplated by the molecular plating technique and then reduced in a flow of pure hydrogen at about 1200°C. The intermetallic compound layer and based on this compound target were analyzed by Scanning electron microscope, energy dispersive spectroscopy and radiography method. Details will be described in the conference
