Atomic properties of actinide ions with particle-hole configurations
M. S. Safronova, U. I. Safronova, M. G. Kozlov
We study the effects of higher-order electronic correlations in the systems with particle-hole excited states using a relativistic hybrid method that combines configuration interac…
Multipolar polarizabilities and hyperpolarizabilities in the Sr optical lattice clock
S. G. Porsev, M. S. Safronova, U. I. Safronova. +1
We address the problem of the lattice Stark shifts in the Sr clock caused by the multipolar and atom-field interactions and by the term nonlinear in lattice intensity and…
Relativistic all-order many-body calculation of energies, wavelengths, and and transition rates for the configurations in tungsten ions
M. S. Safronova, U. I. Safronova, S. G. Porsev +2
Energy levels, wavelengths, magnetic-dipole and electric-quadrupole transition rates between the low-lying states are evaluated for W to W ions with (n = 2 t…
BBR-induced Stark shifts and level broadening in helium atom
T. Zalialiutdinov, D. Solovyev, L. Labzowsky
The precise calculations of blackbody radiation (BBR)-induced Stark shifts and depopulation rates for low-lying states of helium atom with the use of variational approach are prese…
Study of systematic effects in the HfF ion experiment to search for the electron electric dipole moment
A. N. Petrov
The energy splitings for , , hyperfine levels of the electronic state of HfF ion are calculated as functions of the external va…
Zeeman interaction in state of HfF to search for the electron electric-dipole-moment
A. N. Petrov, L. V. Skripnikov, A. V. Titov
We report the theoretical investigation of the suppression of magnetic systematic effects in HfF cation for the experiment to search for the electron electric dipole moment. Th…
