Manufacture of Tl targets by electrodeposition for the study of excitation functions of ²⁰³Pb

Abstract

Natural Tl targets were manufactured by electrochemical deposition on a foil gold backing. The electrochemical parameters were defined after several experiments and reverse pulse potential was chosen to avoid the formation of filaments and dendrites. Once these parameters were established, enriched 205Tl targets were manufactured on a gold foil backing to be used to measure the cross sections for 203Pb production by deuteron induced reactions. The production yield was calculated from our excitation functions and was found to be 54 MBq/µAh in the energy interval 32.5 MeV – 30 MeV.
