Calculation of the energy levels and hyperfine structure for Xe~II, Rn~II, and Og~II ions

T. H. Dinh, V. A. Dzuba, V. V. Flambaum

Energy levels, Landé -factors, and hyperfine-structure constants are calculated for the singly ionized noble-gas atoms Xe II, Rn II, and Og II. The calculations are performed us…

Shift of nuclear clock transition frequency in Th ions due to hyperfine interaction

V. A. Dzuba, V. V. Flambaum

We calculate hyperfine structure of Th and its ions (Th~IV, Th~III, Th~II, Th~I) to reveal the dependence of the nuclear clock frequency on the hyperfine interaction (hfi).…

Effects of electrons on nuclear clock transition frequency in Th ions

V. A. Dzuba, V. V. Flambaum

We perform calculations of the energy shift of the nuclear clock transition frequency Th as a function of the number of electrons in Th ion. We demonstrate that the depende…

Effect of finite nuclear size on the electric quadrupole hyperfine operator

V. A. Dzuba, V. V. Flambaum

We present an expression for the operator of the electric quadrupole hyperfine interaction which takes into account finite nuclear size. We compare the results obtained with the us…

Calculation of hyperfine structure of erbium and fermium

V. A. Dzuba, V. V. Flambaum

A version of the configuration interaction method, which has been recently developed to deal with large number of valence electrons, has been used to calculate magnetic dipole and…
