摘要：

The stales of Pb-208 are calculated in a 24 orbit model space which includes all excitations up to two particles and two holes beyond the closed shell. All of the known low-lying states are reproduced by this moder. The observed distributions of electromagnetic excitation strength from the ground state to low-lying excited states are well described by the model. The double-octupole excitation strength is calculated and found to be concentrated in 0(+), 2(+), and 4(+) states around 5.2 MeV, but it is fragmented over many 6(+) states, in agreement with recent experiments.
