Towards high-resolution laser ionization spectroscopy of the heaviest elements in supersonic gas jet expansion
Resonant laser ionization and spectroscopy are widely used techniques at radioactive ion beam facilities to produce pure beams of exotic nuclei and measure the shape, size, spin and electromagnetic multipole moments of these nuclei. However, in such measurements it is difficult to combine a high eff...

description | Resonant laser ionization and spectroscopy are widely used techniques at radioactive ion
beam facilities to produce pure beams of exotic nuclei and measure the shape, size, spin and
electromagnetic multipole moments of these nuclei. However, in such measurements it is
difficult to combine a high efficiency with a high spectral resolution. Here we demonstrate the
on-line application of atomic laser ionization spectroscopy in a supersonic gas jet, a technique
suited for high-precision studies of the ground- and isomeric-state properties of nuclei
located at the extremes of stability. The technique is characterized in a measurement on
actinium isotopes around the N¼126 neutron shell closure. A significant improvement in the
spectral resolution by more than one order of magnitude is achieved in these experiments
without loss in efficiency. |
