Observation of the distribution of nuclear magnetization in a molecule
S. G. Wilkins, S. M. Udrescu, M. Athanasakis-Kaklamanakis +33
Rapid progress in the experimental control and interrogation of molecules, combined with developments in precise calculations of their structure, are enabling new opportunities in…
A relativistic coupled-cluster treatment of magnetic hyperfine structure of the and states of OH isotopologues
D. P. Usov, Y. S. Kozhedub, A. V. Stolyarov +3
calculations of the parallel component of the magnetic dipole hyperfine structure (HFS) constant have been carried out for hydroxyl radical isotopologues ($^{1…
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…
Impact of ligand (OH) deformation on LuOH rovibrational spectra
Igor Kurchavov, Sergey Prosnyak, Leonid V. Skripnikov +1
Triatomic cation LuOH, featuring near-degenerate, opposite-parity -doublets, offers enhanced sensitivity to - and -violating interactions.…
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…
