Study of thorium in hypersonic gas jets: Ionization potentials of Th and Th
A. Claessens, F. Ivandikov, M. Brasseur +10
Laser ionization spectroscopy was performed on both neutral and singly ionized Th with the aim of identifying the nuclear-clock isomer in the singly charged ionic state of…
multiconfigurational calculations of experimentally significant energy levels and transition rates in Lr I
Joseph S. Andrews, Andrey I. Bondarev, Per Jönsson +4
Large-scale multiconfigurational calculations are conducted on experimentally significant transitions in Lr I and its lanthanide homologue Lu I, exhibiting good agreement with rece…
Laser Resonance Chromatography: First Commissioning Results and Future Prospects
EunKang Kim, Biswajit Jana, Aayush Arya +6
We report first results obtained during the commissioning of the Laser Resonance Chromatography (LRC) apparatus, which is conceived to enable atomic structure investigations in the…
Recent progress in laser spectroscopy of the actinides
Michael Block, Mustapha Laatiaoui, Sebastian Raeder
The interest to perform laser spectroscopy in the heaviest elements arises from the strong impact of relativistic effects, electron correlations and quantum electrodynamics on thei…
Detection of missing low-lying atomic states in actinium
Ke Zhang, Dominik Studer, Felix Weber +10
Two lowest-energy odd-parity atomic levels of actinium, 7s^27p 2P^o_1/2, 7s^27p 2P^o_3/2, were observed via two-step resonant laser-ionization spectroscopy and their respective ene…
Resonance ionization spectroscopy of thorium isotopes - towards a laser spectroscopic identification of the low-lying 7.6 eV isomer of Th-229
Sebastian Raeder, Volker Sonnenschein, Tina Gottwald +5
In-source resonance ionization spectroscopy was used to identify an efficient and selective three step excitation/ionization scheme of thorium, suitable for titanium:sapphire (Ti:s…
