Experimental studies on heavy and superheavy elements are an important field of research to contribute to our understanding of the underlying nuclear structure which stabilizes these nuclei against fission. As the heaviest nuclides are radioactive and often short-lived, they are typically only available in small quantities. Resonant ionization spectroscopy (RIS) and subsequent mass selection proves to be a useful technique to determine atomic and nuclear properties by probing atomic spectra. Additionally, preceding analysis of stable isotopes or lighter homologues of the nuclide under investigation is indispensable to optimize and tailor the techniques for gaining insight into the structure of the target nuclide.
Therefore, an existing setup was further developed for the investigation of elements available off-line and in macroscopic quantities using RIS and a quadrupole mass separator (QMS). As a first result an ionization scheme of thulium was developed for future studies of neutron deficient isotopes of thulium at the GSI facility with the RADRIS technique. In this contribution the setup will be presented, together with laser spectroscopic results and the future prospects will be discussed.
