Laser spectroscopy of nobelium isotopes — •Premaditya Chhetri for the RADRIS collaboration — TU Darmstadt, Darmstadt

Laser spectroscopy of the heaviest elements with Z>100 allows studying the influence of relativistic and QED effects on the atomic shell structure. Furthermore, nuclear ground state properties can be extracted from isotopic shifts and the hyperfine structure of the atomic transitions. The low production rates of a few atoms per second and the so far unknown atomic structure make such studies quite challenging. Applying the Radiation Detected Resonance Ionization Spectroscopy (RADRIS) technique [1] at the SHIP velocity filter at GSI, offered us the possibility to observe the first laser spectroscopic signal on nobelium (Z=102). In this talk the RADRIS setup and the results on laser spectroscopy of the isotopes ^252−254No will be discussed.
