“…These opposite parity states are connected by enhanced transitions, and specifically the E3 moment is the best suited observable to be correlated with intrinsic octupole deformation [75]. Recent Coulomb excitation studies at REX-ISOLDE probed E2 and E3 transitional matrix elements via excitation cross sections and indicate a moderate enhancement of collectivity for 224 Ra and 226 Ra [81,82]. One of the first fast-timing measurements performed at ISOLDE, combined with electron spectroscopy, investigated 228 Ra [83].…”

Related contentNuclear-structure studies of exotic nuclei with MINIBALL P A Butler, J Cederkall and P Reiter AbstractThe advanced time-delayed bgg(t) method has been used at ISOLDE since the relocation of the facility from the synchrocyclotron to the CERN proton synchrotron booster, a quarter of a century ago. The method was designed for precision measurements with low-intensity beams, achieving good efficiency and excellent time resolution with a compact setup. Over this time the technique has evolved to cope with the challenge of measuring lifetimes of complex level schemes of increasingly exotic nuclei populated in β decay. The ISOLDE facility provides unsurpassed opportunities to study many regions of the nuclide chart. The physics case encompasses topics of interest across the nuclide chart, including the evolution of shell structure around neutron shell and subshell closures such as N=20, N=40 and N=50, shape coexistence, and octupole correlations in heavy nuclei. The recently commissioned ISOLDE decay station provides enhanced capabilities that will be fully exploited with the increased beam intensities available at the upcoming HIE-ISOLDE facility.

“…In the recent past, several experimental measurements have been done to study the structure and collectivity in the Pb region [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Apart from this, different class of correlations such as pairing, quadrupole and octupole ones are recently reported [17]. Nuclei in the vicinity of N = 126 are very crucial to understand the astrophysical r process in producing nuclei heavier than A ∼ 190 [5].…”

We present systematic large-scale shell-model calculations for Rn isotopes with A = 207 to 216. For the [207][208][209][210][211][212] Rn isotopes, we perform calculations with KHH7B interaction, while for [213][214][215][216] Rn isotopes with KHPE and KHH7B interactions. The calculated energies and electromagnetic properties are compared with the available experimental data and predicted where experimental data are not available. We also suggest spins and parities of several unconfirmed states available from the recent experimental data. Comprehensive study of several isomeric states from the calculated shell-model configurations and half-lives is also reported.

In the present work, we have performed systematic large-scale shell-model calculations for Rn isotopes with A = 207 to 216. For the 207−212 Rn isotopes, we have performed calculations with KHH7B interaction, while for 213−216 Rn isotopes with KHPE and KHH7B interactions. Calculations have been carried out with the KHH7B in a model space consisting of the proton orbitals d 5/2 , h 11/2 , d 3/2 and s 1/2 below the Z = 82 shell gap, and the h 9/2 , f 7/2 , and i 13/2 above it, and for neutron, the i 13/2 , p 3/2 , f 5/2 , and p 1/2 orbitals are below N = 126 shell gap, and the g 9/2 , i 11/2 , j 15/2 orbitals are above it. The calculations for KHPE interaction are performed in the full Z = 82-126 protonneutron model space with proton orbitals h 9/2 , f 7/2 , f 5/2 , p 3/2 , p 1/2 , and i 13/2 , and neutron orbitals i 11/2 , g 9/2 , g 7/2 , d 5/2 , d 3/2 , s 1/2 , and j 15/2 . The calculated energies and electromagnetic properties have been compared with the available experimental data. We have also analyzed several isomeric states from the calculated shell-model configurations and half-lives. In the case of even Rn isotopes, the 81 + isomeric state is due to seniority v =2, the 141 + and 171 − isomeric states are due to seniority v =4. For the odd Rn isotopes, the 13/21 + isomeric state is due to seniority v =1, the 35/21 + , 43/21 − and 49/21 + isomeric states are due to seniority v = 5. We have also suggested spins and parities of several unconfirmed states from the recent experimental data.
