Theoretical study of electronic structure and spectroscopic properties of the TlO molecule
Alexander V. Oleynichenko, Yuriy A. Demidov
The electronic structure and properties of the thallium monoxide (TlO) molecule, as well as its cation and anion, have been systematically studied using both the relativistic Fock-…
Ionization potential and electron affinity of superheavy element 119: relativistic high-order coupled cluster study with QED corrections
A. R. Saetgaraev, L. V. Skripnikov, I. I. Tupitsyn +5
We report a highly accurate \textit{ab initio} study of the ionization potential (IP) and electron affinity (EA) of element 119. Electronic correlation are treated within the relat…

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…
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…
Recent advancements in atomic many-body methods for high-precision studies of isotope shifts
B. K. Sahoo, S. Blundell, A. V. Oleynichenko +3
The development of atomic many-body methods, capable of incorporating electron correlation effects accurately, is required for isotope shift (IS) studies. In combination with preci…
Radiative lifetime of the A 2Π1/2 state in RaF with relevance to laser cooling
M. Athanasakis-Kaklamanakis, S. G. Wilkins, P. Lassègues +38
The radiative lifetime of the (v=0) state in radium monofluoride (RaF) is measured to be 35(1) ns. The lifetime of this state and the related decay rate $Γ= 2.86(8…
