Abstract: We present systematic calculations of the properties of 11(-) isomers in neutron-deficient Pb184-198 and Po188-200. These states are based on the pi(h(9/2)i(13/2))(Kpi=11-) configuration. They are calculated in the framework of the Hartree-Fock-Bogoliubov method with a Skyrme interaction and density-dependent pairing force. The energies and deformations of the 11(-) states are compared to those of the intruder 0(+) states in both Pb and Po isotopes. In the most neutron-deficient Po isotopes, the calculations predict, below a weakly oblate 11(-) state, another oblate 11(-) state which is even more deformed than the intruder oblate 11(-) state in their Pb isotones. The energies and quadrupole moments of the 11(-) isomers, corresponding to a weakly oblate nuclear shape, are in fair agreement with the available experimental data. (C) 2003 Elsevier B.V.
