“…The present article provides detailed results of calculations within the framework of the IBM with configuration mixing for the 186−196 Pb isotopes, including results for the calculated energy levels, B(E2) values and quadrupole deformations. These results complement previously published calculations on the midshell nucleus 186 Pb [8] and on the calculated isotopic shifts in the neutron-deficient Pb isotopes [7]. The present results for 188 Pb in particular provide an update and extension of the results in Ref.…”

“…In 186,188 Pb, recent experiments [8,9,11] have provided extensive data on excitation spectra and the electromagnetic properties, rendering a thorough test for theoretical approaches. For the heavier 190−196 Pb isotopes, we compare the results of the calculations to the experimental level schemes.…”

In this article we report the results of detailed interacting boson model calculations with configuration mixing for the neutron-deficient Pb isotopes. Calculated energy levels and B(E2) values for 188−196 Pb are discussed and some care is suggested concerning the current classification on the basis of level systematics of the 4 + 1 and 6 + 1 states in 190−194 Pb. Furthermore, quadrupole deformations are extracted for 186−196 Pb and the mixing between the different families (0p-0h, 2p-2h, and 4p-4h) is discussed in detail. Finally, the experimental and the theoretical level systematics are compared.

“…At least one low-lying 0 + state with excitation energy below 1.0 MeV has, to date, been observed in all even-even lead isotopes with neutron number ranging from 100 to 112. Rotational bands based on both prolate [5][6][7] and oblate [8,9] shapes have been observed in 186,188 Pb.…”

Multi-quasiparticle excitation: Extending shape coexistence inA~190neutron-deficient nuclei

et al. 2010

View full text Add to dashboard Cite

Multi-quasiparticle high-K states in neutron-deficient mercury, lead, and polonium isotopes have been investigated systematically by means of configuration-constrained potential-energy-surfacecalculations. An abundance of high-K states is predicted with both prolate and oblate shapes, which extends the shape coexistence of the mass region. Well-deformed shapes provide good conditions for the formation of isomers, as exemplified in 188 Pb. Of particular interest is the prediction of low-lying 10 − states in polonium isotopes, which indicate long-lived isomers.
