Collinear Laser Spectroscopy on Neutron Rich Palladium — •Laura Renth for the ATLANTIS collaboration — Institut für Kernphysik, Technische Universität Darmstadt, Darmstadt, Germany
Collinear laser spectroscopy gives access to isotope shifts and hyperfine parameters at high precision. From this, nuclear charge radii, nuclear magnetic and electric moments and nuclear spins can be determined.
The LASPEC beamline, originally designed for collinear laser spectroscopy at FAIR, has been connected to the Californium Rare Isotope Breeder Upgrade (CARIBU) and is now the central part of ATLANTIS (Argonne Tandem hall LAser bemliNe for aTom and Ion Spectroscopy). Results from its commissioning and a first physics run on neutron-rich palladium isotopes will be presented. Short-lived Pd ions were delivered from CARIBU and neutralized to a fast atomic beam. Laser fluorescence spectroscopy was performed on the isotopes 110, 112−116Pd. Spectra of all stable isotopes (even 102−110Pd and 105Pd) were taken for reference with ions delivered by a laser-ablation ion source. Further measurements will be performed on products of the CARIBU successor nuCARIBU.
