Level energies and decay rates of both negative and positive parity levels of {sup 206,204}Pb have been calculated through mixed-configuration shell model calculations using the modified surface delta interaction (MSDI), the Schiffer-True central interaction, and another two-body interaction. These calculations were all carried out with a full six-orbit neutron hole space. The predicted low-lying levels with the MSDI are in excellent agreement with experiments, accounting for the energies, spins, and parities of essentially all levels below 3 MeV excitation energy except known particle-hole collective excitations in both nuclei. Almost all calculated {ital E}2 and {ital M}1 transition rates are consistent with measured branching ratios for {gamma}-ray decay of excited levels. The comparison of the observed and calculated levels demonstrates the important role played by the neutron-hole {ital i}{sub 13/2} configuration in the levels of {sup 204}Pb and {sup 206}Pb, and interprets an apparent discrepancy over the character and energy spacings of 0{sup +} levels in {sup 204}Pb.
