Fast configuration-interaction calculations for nobelium and ytterbium
V. A. Dzuba, V. V. Flambaum, M. G. Kozlov
We calculate excitation energies for low states of nobelium, including states with open subshell. An efficient version of the many-electron configuration-interaction method fo…
Hyperfine induced transitions 1S0 - 3D1 in Yb
M. G. Kozlov, V. A. Dzuba, V. V. Flambaum
Parity violation experiment in Yb is made on the strongly forbidden M1 transition 6s^2 1S0 \to 5d6s 3D1. The hyperfine mixing of the 5d6s 3D1 and 5d6s 3D2 levels opens E2 channel,…
Nobelium energy levels and hyperfine structure constants
S. G. Porsev, M. S. Safronova, U. I. Safronova +2
Advances in laser spectroscopy of superheavy () elements enabled determination of the nuclear moments of the heaviest nuclei, which requires high-precision atomic calculatio…
Atomic structure calculations of super heavy noble element oganesson (Z=118)
Bryce G. C. Lackenby, Vladimir A. Dzuba, Victor V. Flambaum
We calculate the spectrum and allowed E1 transitions of the superheavy element Og (Z=118). A combination of configuration interaction (CI) and perturbation theory (PT) is used (Dzu…
Screening of oscillating external electric field in atoms
V. A. Dzuba, J. C. Berengut, J. S. M. Ginges +1
We study the screening of a homogeneous oscillating external electric field in noble-gas atoms using atomic many-body calculations. At zero frequency of the oscillations ($ω=…
Calculation of atomic spectra and transition amplitudes for superheavy element Db (Z=105)
Bryce G. C. Lackenby, Vladimir A. Dzuba, Victor V. Flambaum
Atomic spectra and other properties of superheavy element dubnium (Db, Z=105) are calculated using recently developed method combining configuration interaction with perturbation t…
