Nuclear quadrupole moments ofS33andS35

Abstract
The nuclear quadrupole moments of S33 and S35 are studied using numerical multiconfigurational Hartree-Fock (MCHF) calculations on S (2 P3/2). A newly developed finite-element MCHF program allowing very large configuration-interaction expansions is used. The 3p5 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 S33 and S35 become -0.0678(13) and 0.0471(9) b, respectively.
