Ab initio study and assignment of electronic states in molecular RaCl
T. A. Isaev, A. V. Zaitsevskii, A. Oleynichenko +5
Radium compounds have attracted recently considerable attention due to both development of experimental techniques for high-precision laser spectroscopy of molecules with short-liv…
Ab initio relativistic treatment of the intercombination Cameron system of the CO molecule
Nikolai S. Mosyagin, Alexander V. Oleynichenko, Andrei Zaitsevskii +3
The intercombination Cameron system of carbon monoxide has been computationally studied in the framework of multi-reference Fock space coupled cluster method with th…
The branching ratio of intercombination transitions in the RbCs molecule: measurements and calculations
Valts Krumins, Artis Kruzins, Maris Tamanis +6
We observed the laser-induced fluorescence (LIF) spectra of the RbCs molecule excited from the ground state by the Ti:Sapphire laser. Th…
Diagonal and off-diagonal hyperfine structure matrix elements in KCs within the relativistic Fock space coupled cluster theory
Alexander V. Oleynichenko, Leonid V. Skripnikov, Andrei Zaitsevskii +2
The four-component relativistic Fock space coupled cluster method is used to describe the magnetic hyperfine interaction in low-lying electronic states of the KCs molecule. Both di…
Towards High Performance Relativistic Electronic Structure Modelling: The EXP-T Program Package
Alexander V. Oleynichenko, Andréi Zaitsevskii, Ephraim Eliav
Modern challenges arising in the fields of theoretical and experimental physics require new powerful tools for high-precision electronic structure modelling; one of the most perspe…
