The lifetime of the 2+1 state of 210Pb was measured in the 208Pb(18O, 16O)210Pb two-neutron transfer reaction by γ-ray spectroscopy employing the recoil-distance Doppler-shift method. The extracted absolute B(E2)\downarrow value of 119 + 9- 8 \hspace-0pt e2fm4 is consistent with previously reported measurements, but with significantly improved precision. The available experimental data for the 2+1-4+1-6+1-8+1 multiplet are compared with shell-model calculations based on the well-established Kuo-Herling interaction. The new B(E2)\downarrow value agrees well with the shell-model prediction, providing evidence that the properties of the 2+1 and 8+1 states of 210Pb can be consistently described together within the nuclear shell-model framework.
