Abstract
Reorientation effect and multiple Coulomb excitation measurements have been performed for198, 200, 202, 1204Hg. By measuring particle spectra after Coulomb excitation of an enriched198Hg target with4He and16O beams, a positive quadrupole moment of Q2 = 0.66±0.18 eb (for negative interference) or Q2=0.80±0.18 eb (for positive interference) andB(E2,0→2)=0.991±0.006 e2b2 were obtained. All otherB(E2) values and quadrupole moments were determined relative to these numbers from preciseγ-ray yields obtained from Coulomb excitation of a frozennatHg target with4He and16O projectiles. Oblate shapes of all Hg isotopes were found. The data have been interpreted in terms of triaxial rotation and anharmonic vibrations.
