Coulomb excitation of re-accelerated Rn-208 and Po-206 beams

In the present study, B(E2; 2+ → 0+) values have been measured in the 208Rn and 206Po nuclei through Coulomb excitation of re-accelerated radioactive beams in inverse kinematics at CERN-ISOLDE. The resulting B(E2; 2+ → 0+) in 208Rn is ∼0.08 e2b2. These nuclei lie in, or at the boundary of the region...

Zusammenfassung:	In the present study, B(E2; 2+ → 0+) values have been measured in the 208Rn and 206Po nuclei through Coulomb excitation of re-accelerated radioactive beams in inverse kinematics at CERN-ISOLDE. The resulting B(E2; 2+ → 0+) in 208Rn is ∼0.08 e2b2. These nuclei lie in, or at the boundary of the region where seniority scheme should persist. However, contributions from collective excitations may be present when mov- ing away from the N = 126 shell closure. To date, surprisingly little is known of the transition probabilities between the low-spin states in this region.
