Abstract | The IS475 collaboration conducted Coulomb-excitation experiments with postaccelerated radioactive (220)Rn and (224)Ra beams at the REX-ISOLDE facility. The beam particles (E(beam) ≈ 2.83 MeV/u) were Coulomb excited using (60)Ni, (114)Cd, and (120)Sn scattering targets. De-excitation γ-rays were detected employing the Miniball array and scattered particles were detected in a silicon detector. Exploiting the Coulomb-excitation code GOSIA for each nucleus several matrix elements could be obtained from the measured γ-ray yields. The extracted langle3(−)||Ê3||0(+)rangle matrix element allows for the conclusion that, while (220)Rn represents an octupole vibrational system, (224)Ra has already substantial octupole correlations in its ground state. An observation that has implications for the search of CP-violating Schiff moments in the atomic systems of the adjacent odd-mass nuclei. |
