Laser Spectroscopy at Argonne National Laboratory
ORAL · Invited
Abstract
The ATLAS facility offers excellent opportunities to utilize slow and stopped radioactive beams for nuclear structure research. The newly commissioned nuCARIBU source provides beams of neutron-induced U-235 fission fragments at low energies (20 keV) for experiments. At the N=126 factory, heavy isotopes in the lead region produced in flight via multinucleon transfer (MNT) reactions are stopped in a gas cell. At both beam stations, laser spectroscopy instrumentation is being developed to complement existing decay spectroscopy and mass measurement experiments.
I will report on the progress of the laser spectroscopy program at ATLAS, with a focus on the ATLANTIS laser spectroscopy beamline at nuCARIBU, which recently delivered its first results on charge radii of neutron-rich ruthenium isotopes. Currently, this beamline is being upgraded to implement resonance ionization spectroscopy (RIS) for enhanced sensitivity compared to the existing laser-induced fluorescence detection. The N=126 factory laser beamline is presently under construction. I will provide an overview of the implementation, discuss technical developments, and outline the physics program that can be performed there soon.
