“…In this work, we have adopted the large quenching in the weak coupling constants, also the mesonic enhancement factor ǫ mec = 2.01 ± 0.05 [8,9] in the rank-0 axial-charge matrix element γ 5 corresponding to ∆J = 0 transitions. Present study will add more information to Berry et al [4] work.…”

“…In this experiment, they have observed several new excited states and β feeding branching ratio between the energy range 2.6-4.0 MeV for 207 Tl through β − decay of 207 Hg. In this work [4] shell-model results for the energy spectra using KHM3Y interaction have been reported, although, no shell-model results for the log f t values are reported. These new data motivated us to perform large scale shell-model calculations for the log f t values corresponding to β − decay of 207 Hg(9/2 + g.s.…”

“…Wilson et al [3] have measured the high-spin states above the 3.813 MeV in the nucleus 207 Tl and also they have reported the shell-model results corresponding to t = 1 truncation (where t is the number of nucleons excitation across the 208 Pb core) for both protons and neutrons. After that, the same group measured the new excited states in 207 Tl through the β − decay of 207 Hg in the energy range of 2.6-4.0 MeV [4]. In these experiments, several new excited states have been identified in 207 Tl.…”

In this work, we have performed large scale shell-model calculations for the first-forbidden β − decay of 207 Hg into the one-proton-hole nucleus 207 Tl corresponding to the recently available experimental data from ISOLDE-CERN [ T. A. Berry et al., Phys. Rev. C 101, 054311 (2020)]. We have used the one-particle one-hole (1p-1h) truncation for both protons and neutrons simultaneously across the doubly-shell closure at 208 Pb in the final states of 207 Tl. In our calculations we have also considered the effect of mesonic enhancement ǫmec = 2.01 ± 0.05 in the rank-0 for the axial-charge matrix element γ5. Here, we have calculated the log f t values from the ground-state of 207 Hg to the several excited states of 207 Tl and obtained a good agreement between calculated and the experimental data. In the experimental data spin and parity for the some states are not yet confirmed, thus based on the shell-model results for the log f t values we have given the prediction for these states.

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.
