Precise experimental control and interrogation of molecules and calculations of their structure are enriching the investigation of nuclear and particle physics phenomena. Molecules containing heavy, octupole-deformed nuclei, such as radium, are of particular interest. Here, we report precision laser spectroscopy measurements and theoretical calculations of the structure of the radioactive radium monofluoride molecule 225Ra19F. Our results reveal ...

We present two newly constructed experimental setups-REBEL (Resonant Excitation of Beams with Electromagnetic fields and Lasers) and STRIPE (Stopping and Trapping of Radioactive Isotopes for Precision Experiments)-integrated into a single offline beamline at KU Leuven. REBEL is designed for collinear laser spectroscopy of ion bunches, including isobaric separation with a multi-reflection time-of-flight mass spectrometer, enabling ...

Highly accurate and precise electronic structure calculations of heavy radioactive atoms and their molecules are important for several research areas, including chemical, nuclear, and particle physics. Ab initio quantum chemistry can elucidate structural details in these systems that emerge from the interplay of relativistic and electron correlation effects, but the large number of electrons complicates the calculations, and the scarcity of ...

A new linear Paul trap section has been constructed to replace the existing bunching section of the radiofrequency quadrupole (RFQ) cooler-buncher at the IGISOL radioactive ion beam facility. The cooler-buncher is used to transform a continuous ion beam to temporally short bursts of ions. The new miniaturised cooler-buncher section produces significantly shorter bunches in time, required by the new Multi-Reflection Time-of-Flight Mass ...
