Abstrakt: For nuclear reaction studies, thin metallic osmium targets, either natural or isotopically enriched (Os-192) of 200-300 µg/cm2 thicknesses deposited on a thin carbon backing are required. A challenging method was successfully performed at GANIL involving firstly the preparation of an aqueous solution of osmium tetrachloride, then its electro-deposition onto a thick copper backing (100 µm); this process was followed by the evaporation of a thin carbon layer (≈40 µg/cm²) and finally the dissolution of the copper material.
