Abstract: | Coulomb excitation studies have been performed to measure transition probabilities of collective quadrupole vibrational states in 180Hf. The I = 2 level of the Kπ = 2+ collective γ-band is established at 1200.5 keV with B(E2)exc = (11.0 ± 1.1) × 10?50e2 · cm4 (3.6 ± 0.4 s.p.u.). The angular distribution of the de-exciting γ-rays from this level yields δ = 9.6+22?5.8 or, less likely, 0.7 ± 0.2 for the 1107.2 keV 2γ+ → 2g+ transition. The B(E2)exc for any KπI = 0+2 stateorother 2+ states up to 1500 keV is less than 5 × 10?51e2 · cm4 (< 0.2. s.p.u.). |
