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…
On the rank-reduced relativistic coupled cluster method
Alexander V. Oleynichenko, Artem S. Rumiantsev, Andrei Zaitsevskii +1
An efficiency of the Tucker decomposition of amplitude tensors within the single-reference relativistic coupled cluster method with single and double excitations (RCCSD) was studie…
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…
Finite-order method to calculate approximate density matrices in the Fock-space multireference coupled cluster theory
Alexander V. Oleynichenko, Andrei Zaitsevskii, Leonid V. Skripnikov +1
An efficient approach to calculate approximate pure-state and transition reduced density matrices in the framework of the multireference relativistic Fock-space coupled cluster (FS…
Ionization potential of radium monofluoride
S. G. Wilkins, H. A. Perrett, S. M. Udrescu +43
The ionization potential (IP) of radium monofluoride (RaF) was measured to be 4.969(2)[10] eV, revealing a relativistic enhancement in the series of alkaline earth monofluorides. T…
Relativistic coupled cluster calculations of the electron affinity and ionization potentials of lawrencium
Yangyang Guo, Lukáš F Pašteka, Yuichiro Nagame +4
The calculations of the first and the second ionization potentials of lawrencium and lutetium and the electron affinity of lawrencium are performed within the relativistic coupled…
