文摘

Previously reported preparation method for Pd-based intermetallic targets (Usoltsev, et al., 2012) has been successfully applied for producing two stationary ²⁴³Am/Pd targets. Both targets have been irradiated at the U-400 cyclotron at Flerov Laboratory of Nuclear Reactions Dubna (Russian Federation) using high intensity beams (up to 0.83 渭A_part) of ⁴⁸Ca¹⁸⁺. Alpha-particle spectroscopy and light microscopy allowed for a comprehensive characterization of the intermetallic targets before and after irradiation. A ^natNd/Pd intermetallic target and a solely electroplated ²⁴³Am/Ti target were similarly investigated for comparison.
