The excited states in this nucleus were populated via two consecutive electron capture decays from 206Rn. The parent isotope was produced in the 194Pt(16O,4n)206Rn fusion-evaporation reaction at the FN-Tandem facility at the Institute for Nuclear Physics, University of Cologne. The previously known value for the lifetime of the 4_1+ state in 206Po was confirmed using the generalized centroid difference (GCD) method. The lifetime of the 6_1+ state was determined from β decay in the first application of the GCD method for x-ray–γ coincidences. A Monte Carlo based approach was applied to address the indirect population of the 6_1+ state by the decay of 206At. The experimental results were examined in the context of the transition of single-particle excitations to collective behavior in the neutron-deficient Po isotopes. The obtained B(E2;6_1+→4_1+) value suggests that for the 6_1+ states in even-even Po isotopes the transition from a noncollective regime at N=126 to a collective regime occurs at N≤120.
