Ab initio calculations of the electronic structure of Ac
Genevieve Geehan, Marten Luit Reitsma, Johan David Polet +3
Accurate spectroscopic investigations of the heaviest elements are inherently challenging, due to their short lifetimes and low production yields. Success of such measurements requ…
Laser Resonance Chromatography of Th in He: an ab initio investigation
Giorgio Visentin, Anastasia Borschevsky, Larry A. Viehland +2
We propose a laser resonance chromatography (LRC) experiment on Th, with the goal of detecting the ion's electronic ground F state and metastable $7…
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…
Transport property predictions for laser resonance chromatography on Rf (Z = 104)
Giorgio Visentin, Harry Ramanantoanina, Anastasia Borschevsky +5
We propose a theoretically designed laser resonance chromatography (LRC) experiment on Rf (Z = 104) drifting in He buffer gas. To this end, we first developed a four-level rate…
State-specific ion mobilities of Lr^+ (Z = 103) in helium
Harry Ramanantoanina, Anastasia Borschevsky, Michael Block +2
Ion mobilities of Lr^+ (Z = 103) and of its lighter chemical homolog Lu^+ (Z = 71) in helium were calculated for the ground state ^1S_0 and the lowest metastable state ^3D_1. To th…
Electronic structure of Rf^+ (Z = 104) from ab initio calculations
Harry Ramanantoanina, Anastasia Borschevsky, Michael Block +1
We report calculation of the energy spectrum and the spectroscopic properties of the superheavy element ion: Rf^+. We use the 4-component relativistic Dirac-Coulomb Hamiltonian and…
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…
Mobility of the Singly-Charged Lanthanide and Actinide Cations: Trends and Perspectives
Giorgio Visentin, Mustapha Laatiaoui, Larry A. Viehland +1
The current status of gaseous transport studies of the singly-charged lanthanide and actinide ions is reviewed in light of potential applications to superheavy ions. The measuremen…
Laser Resonance Chromatography of Superheavy Elements
Mustapha Laatiaoui, Alexei A. Buchachenko, Larry A. Viehland
Optical spectroscopy constitutes the historical path to accumulate basic knowledge on the atom and its structure. Former work based on fluorescence and resonance ionization spectro…
Exploiting transport properties for the detection of optical pumping in heavy ions
Mustapha Laatiaoui, Alexei A. Buchachenko, Larry A. Viehland
We present a kinetic model for optical pumping in Lu and Lr ions as well as a theoretical approach to calculate the transport properties of Lu in its ground and…
High-precision ab initio calculations of the spectrum of Lr
E. V. Kahl, J. C. Berengut, M. Laatiaoui +2
The planned measurement of optical resonances in singly-ionised lawrencium (Z = 103) requires accurate theoretical predictions to narrow the search window. We present high-precisio…
