Contribution
It demonstrates a method to evaluate correlation effects in MCDHF calculations for atomic EDMs, providing a converged series approach.
Findings
Correlation effects dominate the EDM calculation.
Converged multiconfiguration expansions accurately evaluate correlation effects.
Results advance understanding of atomic EDMs induced by nuclear Schiff moments.
Abstract
The multiconfiguration Dirac-Hartree-Fock theory (MCDHF) has been employed to calculate the electric dipole moment of the 7s6d 3D2 state of radium induced by the nuclear Schiff moment. The results are dominated by valence and core-valence electron correlation effects. We show that the correlation effects can be evaluated in a converged series of multiconfiguration expansions.
