“…Now, we present and discuss our calculated results. In Figure 1, we present the calculated energy levels of 210 Po in the upper panel and those of 212 Rn in the lower panel, in comparison with experimental data [4,51]. One can see in Figure 1 that our calculated results agree with experimental data reasonably.…”

“…One of the key issues is the shell structure in these nuclei, i.e., the robustness of the N = 126 shell gap and the existence of the foreseen Z = 92 subshell. Important experimental progresses have been made along this line in recent years; see, e.g., [1][2][3][4][5][6][7]. Theoretically, characterized by large model spaces and reflections of various correlations, the nuclei in the 208 Pb region are challenging subjects.…”

In this paper, we study yrast states of two N = 126 isotones 210Po and 212Rn using the nucleon-pair approximation with particle–hole excitations and using a low-momentum interaction Vlow−k renormalized from the free CD-Bonn NN potential. An overall good agreement with experimental level structures, B(E2)s, and B(E3)s, is achieved. We also calculate the probabilities of neutron particle–hole excitations in these yrast states, with a focus on negative-parity states, which reflect the roles played by the neutron negative-parity configurations of one-particle-one-hole excitations across the N = 126 shell gap and the negative-parity configurations of valence proton particles involving the 0i13/2 orbit. The N = 126 shell gap is discussed in terms of energies of neutron one-particle-one-hole excitations.

“…The shell model is an essential tool for the systematic understanding of the nuclear structure. Recently, it has been employed in describing light, proton-rich, exotic nuclei and the related isospin symmetry breaking [30][31][32][33], interpreting the shell evolution in the medium mass region [34,35], reproducing isomeric states in the medium [36,37] and heavy nuclei [38][39][40], and investigating the α-decay properties of heavy-mass nuclei [41,42].…”

Within the framework of the configuration–interaction shell model, the present work applies three effective interactions to investigate the effects of the cross-shell excitation on F and Ne isotopes around N = 20, which are significantly proton–neutron asymmetric, and have different properties compared with the proton–neutron symmetric nuclei. It is shown that cross-shell excitation is necessary in order to reproduce separation energies, neutron drip lines, and low-energy levels of these isotopes. Furthermore, the cross-shell excitation of (0–5)ħω is suggested to be important in the description of 29F and 30Ne. However, the three interactions are insufficient in describing the bound structure of 29,31Ne, and provide inconsistent shell structures and evolutions in the target nuclei. Their cross-shell interactions are suggested to be improved.

“…Theoretical results using the semiempirical shellmodel and deformed independent particle model (DIPM) are also reported. In another recent experiment at Legnaro National Laboratory in Italy [21], a low-lying level scheme of 212 Rn has been populated. In this experiment, several non-yrast states based on πh 4 9/2 and πh 3 9/2 f 7/2 configurations have been identified.…”

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.
