High-resolution spectroscopy of fermium-255 at the RISIKO mass separator — •Mitzi Urquiza-González for the Fermium collaboration — Division HÜBNER Photonics, Hübner GmbH & Co KG, 34123 Kassel, Germany
Laser spectroscopy measurements can provide information about fundamental properties of both atomic and nuclear structure. Such measurements are of particular importance for the heaviest actinides and superheavy elements, where data is sparse. During the last measurement campaign at the RISIKO mass separator facility in the Institute of Physics in the Johannes Gutenberg University Mainz (JGU), nine successive samples, consisting of 108 to 109 atoms, were used to study the atomic and nuclear structure of 255Fm (Z=100).
This presentation will focus on the hyperfine structure (HFS) of 255Fm for two different excited levels, from which the hyperfine coupling constants have been determined.
