Electrodeposition of carrier-free 57Co on rhodium as an approach to the preparation of Mössbauer sources

Electrodeposition of carrier-free 57Co on a rhodium matrix as the first step of preparing Mössbauer sources was studied. To optimize the plating parameters, the influences of current density, volume and pH of the electrolyte solution, shape, thickness, and surface area of the rhodium cathode, mode of cathode pretreatment, concentration of 57Co and duration of electrolysis were investigated.
