Preparation of actinide samples for applications in fundamental physics and chemical studies — •A. T. Loria Basto1,2, C. Mokry1,2, J. Runke1,3, Ch .E. Düllmann1,2,3, and D. Renisch1,2 — 1JGU, Mainz, Germany — 2HIM, Mainz, Germany — 3GSI, Darmstadt, Germany
Samples of radioisotopes serve as sources and targets in many basic chemistry and physics related research projects. Our group specializes in the production of tailor-made samples, for which a variety of parameters have to be considered. The main ones include isotopic purity, layer thickness and homogeneity as well as geometry. We present the methods available at JGU and within our collaboration network to produce, separate and characterize radionuclide samples, mainly of actinide isotopes. We also highlight the production and characterization of experiment-specific samples and give an overview of applications in Mainz as well as in national and international collaborations.
