Relativistic atomic structure calculations in support of spectroscopy
L. F. Pašteka, E. Eliav, M. L. Reitsma +1
Theory can provide important support at all the stages of spectroscopic experiments, from planning the measurements to the interpretation of the results. Such support is particular…

Theoretical determination of the ionization potentials of ScF, YF, LaF and AcF
Aleksandra A. Kyuberis, Lukas F. Pasteka, Ephraim Eliav +4
We present a comprehensive theoretical study of the ionization potentials of the MF (M = Sc, Y, La, Ac) molecules using the state-of-the-art relativistic coupled cluster approach w…
