Nuclear Moments and Charge Radii of Neutron-Rich Palladium Isotopes — •Laura Renth for the ATLANTIS collaboration — Institut für Kernphysik, Technische Universität Darmstadt, Darmstadt, Germany
We present the first experimental results taken at the new collinear laser spectrosocpy setup ATLANTIS (Argonne Tandem hall LAser beamliNe for aTom and Ion Spectroscopy) at the Argonne National Laboratory. Short-lived exotic isotopes are generated from the CARIBU source, which collects 252Cf fission fragments in a gas catcher. After mass speparation, the isotopes of interest are transported at a beam energy of 27keV to the laser spectroscopy setup.
The hyperfine spectra of neutron rich palladium iostopes 112−116,118Pd will be presented as well as the differential mean-square nuclear charge radii, nuclear moments and nuclear spins. These properties add insights in the physics of nuclear shell strucuture evolution, which are discussed in this talk.
