“…The results also indicate that the synthesized final products were composed by Co particles on the surface of Rh foil. In a previous study, a relatively low vacuum 10 -2 hPa under an inert Ar gas atmosphere was maintained during the diffusion process [4][5]. The diffusion yield of Co atoms into the Rh matrix is increased, with the rise in both the annealing temperature and heating time.…”

To establish the coating conditions for 57 Co, non-radioactive Co ions are dissolved in an acid solution and electroplated on to a rhodium plate. The thermal diffusion of electroplated Co into a rhodium matrix was studied to apply a 57 Co Mössbauer source. The procedure to form a Co deposited onto Rh foil was established using two different electroplating baths: the acid-based buffer (pH 3) containing boric acid, sodium chloride, and saccharin, and the alkaline-based buffer (pH 10) containing hydrazine hydrate and ammonium citrate. The influence of different annealing conditions was investigated. From the results, the best diffusion degree of electrodeposited Co onto the rhodium matrix was obtained in an annealing process performed at 1100°C for 3 h in vacuum over10 -5 hPa.

“…After the process of 58 Ni electroplating onto the target materials, 58 Ni was irradiated with a proton beam [4]. An electroplating process was applied to form radioisotope 57 Co onto a metal sheet [5][6]. To remove the gamma ray recoil energy of 57 Co, it was diffused into metals such as Cu, Au, Fe, Pt, Rh, and Pd.…”
