It contains F147100100016 0.02% Nd, 0.02% Gd, <0.01% Sm impurities. 151Eu F147100100017 targets were prepared by electrodeposition from F147100100018 isopropanol solution on 2 mu-m thick titanium foil. F147100100019 METHOD (STTA,EDEG) Up to 10 151Eu/Ti target foils were F147100100020 irradiated in one run using the conventional stack F147100100021 foils technique. Apart from the target foils, the F147100100022 stack also contained 9 mu-m Al and 13 mu-m Cu F147100100023 monitors for controlling the beam parameters, and F147100100024 aluminum degraders (53-159 mu-m).
