The lifetimes of the first excited 2+ and 4+ states in 206Po were measured using the recoil-distance Doppler-shift method. The experimental results were compared to large-scale shell-model calculations that describe the deduced transition probabilities well. Those calculations were extended to the neighboring 204,208Po isotopes giving a good overall description of the yrast states. However, the calculations underpredict the energies of the 6_1+ and 8_1+ states, which suggests that further improvement of the proton-neutron interaction is required.
