First demonstration of electrodeposition of ²³³Pa — •Andreas Oberstedt¹, Magdalena Flenéus¹, Carolina Gustafsson¹, Birger Fogelberg², and Elisabet Ramström² — ¹Dept. of Natural Sciences, Örebro University, SE-70182 Örebro — ²Dept. of Radiation Science, Uppsala University, SE-61182 Nyköping

The isotope ²³³Pa plays an important role in accelerator driven systems for energy production using new and advanced fuel cycles involving ²³²Th and ²³³U, since it is an intermediate isotope in the formation of the main fuel ²³³U. In order to measure necessary cross section data, one needs samples with a sufficient amount of ²³³Pa, basically due to its very short half-life of T_1/2=27.0 d. Earlier experiments with other actinides have shown that electrodeposition (or molecular plating) is a superior method to prepare thin and homogeneous targets. We tested this method for the first time successfully for protactinium using a 2,6 Dimethyl - 4 heptanol (DIBC) solution.
