    Observation of a promethium complex in solution

    Lanthanide rare-earth metals are ubiquitous in modern technologies1,2,3,4,5, but we know little about chemistry of the 61st element, promethium (Pm)6, a lanthanide that is highly radioactive and inaccessible. Despite its importance7,8, Pm has been conspicuously absent from the experimental studies of lanthanides, impeding our full comprehension of the so-called lanthanide…

    Preparation of Actinide Targets at Oregon State University

    We describe the preparation of actinide targets at Oregon State University. The preparation of the actinide fluorides is done by an aqueous precipitation procedure with yields of greater than 90%. A dual glove box system is used for the preparation of the fluorides of the high specific activity actinides and the subsequent vapor deposition. We compare and contrast targets…
