Abstract: | Measurements of the reorientation effect for the first excited 2+ states in200, 202, 204Hg were performed by exploiting the dependence of theγ-ray yield on Q2+ for different projectiles. For200Hg, a positive quadrupole moment of Q2=0.96±0.11 eb (for negative interference) or Q2=1.11±0.11 eb (for positive interference) was determined indicating an oblate shape. Small positive Q2 values were also found for202Hg and204Hg. Nine B(E2) values for excitation of the 2+, 2+′ and 4+ states in196–204Hg measured. |
