Chemical and physical properties of the heaviest elements are strongly influenced by relativistic effects which can result in deviations from the periodicity predicted by the periodic table of elements. Systematic mobility measurements on monoatomic lanthanide ions previously proved a dependence of ion-atom interactions on the underlying electronic configuration, providing a way to measure these deviations [Laatiaoui2012]. Mobility studies are presently being extended to the actinides which are expected to have more pronounced deviations from periodicity. In our experiment, element-selective ion production is provided by two-step photo ionization from a filament sample in an argon filled drift cage. In my talk, experimental approach, first results and future plans are presented.
