“…In the case of 213 Bi isotope due to huge dimension, we have allowed four valance neutrons which are above the N = 126 to occupy in only three neutron orbitals 1g 9/2 , 0i 11/2 , and 0j 15/2 . Recently, our group employed KHH7B and KHM3Y effective interactions in the following [5,[44][45][46]. SM calculations in the extended model space (with KHM3Y interaction) compared to the previous studies [34,47] can be helpful in investigating the different spectroscopic properties of Bi isotopes.…”

In this work, we have performed systematic shell-model calculations for Bi isotopes with $A=$ 204-213 using KHH7B and KHM3Y effective interactions. We have reported yrast and non-yrast shell-model states corresponding to the available experimental data. From the comparison with the experimental data, we could assign spin and parity of several unconfirmed states. We have also calculated electromagnetic properties and compared them with the available experimental data and predicted where experimental data are not available. This study also includes a detailed discussion of multiple isomeric states based on computed shell-model configurations and their respective half-lives.

Heavy neutron-rich nuclei are of great interest. Phenomena like shell evolution ($$N\sim 126$$ N ∼ 126 , $$Z\sim 82$$ Z ∼ 82 ), prolate–triaxial–oblate–spherical shape evolution ($$Z=$$ Z = 70–80), possible deformed shell closures or structure change in the rare-earth region are under intense scrutiny. This latter is closely linked to the rare-earth r-process peak, while the $$N \sim 126$$ N ∼ 126 nuclei are connected to the third r-process peak at $$A \sim 195$$ A ∼ 195 . Recent technical developments (e.g. increasing beam intensities at fragmentation facilities, new detection systems) provided huge amount of new experimental data, published in the last decade, allowing to probe structure and astrophysical models. Experimental methods and recent results are reviewed and future opportunities discussed.
