Abstract
The nuclear quadrupole moments of and are studied using numerical multiconfigurational Hartree-Fock (MCHF) calculations on ). A newly developed finite-element MCHF program allowing very large configuration-interaction expansions is used. The 3 valence correlation decreases the electric field gradient with about 12%, but core-valence polarization increases the electric field gradient with about 14% of the Hartree-Fock value. The final values for the nuclear quadrupole moments of and become -0.0678(13) and 0.0471(9) b, respectively.
