Multiconfiguration Dirac-Hartree-Fock calculations of atomic electric dipole moments of 225^Ra, 199^Hg, and 171^Yb
Laima Radziute, Gediminas Gaigalas, Per Jonsson +1
The multiconfiguration Dirac-Hartree-Fock (MCDHF) method has been employed to calculate atomic electric dipole moments (EDM) of 225^Ra, 199^Hg, and 171^Yb. For the calculations of…
Toward Calculations with Spectroscopic Accuracy: the 2s2.2p 2Po_{3/2} - 2s2p2 4P_{5/2} Excitation Energy in Boron
Charlotte Froese Fischer, Simon Verdebout, Michel Godefroid +3
No lines have been observed for transitions between the doublet and quartet levels of B I. Consequently, energy levels based on observation for the latter are obtained through extr…
The effect of an external magnetic field on the determination of E1M1 two-photon decay rates in Be-like ions
Jon Grumer, Wenxian Li, Dietrich Bernhardt +6
In this work we report on ab initio theoretical results for the magnetic field induced 2s2p ^3P_0 - 2s^2 ^1S_0 E1 transition for ions in the beryllium isoelectronic sequence betwee…
Theoretical investigations on magnetic field induced $2p^53s^3P_{0,2} - 2p^6^1S_0$ transitions in Ne-like ions without nuclear spin
Jiguang Li, Jon Grumer, Wenxian Li +6
We report theoretical results for magnetic field induced $2p^53s^3P_{0,2} - 2p^6^1S_0$ E1 transitions in Ne-like ions with zero nuclear spin (I=0) between Mg III and Zn XXI as well…
A Partitioned Correlation Function Interaction approach for describing electron correlation in atoms
S. Verdebout, P. Rynkun, P. Jönsson +3
Traditional multiconfiguration Hartree-Fock (MCHF) and configuration interaction (CI) methods are based on a single orthonormal orbital basis (OB). For atoms with complicated shell…
