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…
Theoretical study of transition matrix elements in cadmium for vacuum-ultraviolet generation in Th nuclear clock applications
Gleb Penyazkov, Yanmei Yu, Leonid V. Skripnikov +1
The relativistic Fock-space coupled-cluster methods are applied to the cadmium atom. A large number of transition energies and matrix elements are calculated for the $ ^{…
Laser spectroscopy and CP-violation sensitivity of actinium monofluoride
M. Athanasakis-Kaklamanakis, M. Au, A. Kyuberis +39
The apparent invariance of the strong nuclear force under combined charge conjugation and parity (CP) remains an open question in modern physics. Precision experiments with heavy a…
Electric field dependent g factors of ThF
Alexander Petrov, Leonid Skripnikov
The g-factors for , , hyperfine levels of the ground electronic state of the ThF cation are calculated as functions of the external e…
Pinning down electron correlations in RaF via spectroscopy of excited states and high-accuracy relativistic quantum chemistry
M. Athanasakis-Kaklamanakis, S. G. Wilkins, L. V. Skripnikov +53
We report the spectroscopy of the 14 lowest excited electronic states in the radioactive molecule radium monofluoride (RaF). The observed excitation energies are compared with full…
