Lifetimes of prolate intruder states in $^{186}\mathrm{Pb}$ and oblate intruder states in $^{194}\mathrm{Po}$ have been determined by employing, for the first time, the recoil-decay tagging technique in recoil distance Doppler-shift lifetime measurements. In addition, lifetime measurements of prolate states in $^{188}\mathrm{Pb}$ up to the ${8}^{+}$ state were carried out using the recoil-gating method. The $B(E2)$ values have been deduced from which deformation parameters $|{\ensuremath{\beta}}_{2}|=0.29(5)$ and $|{\ensuremath{\beta}}_{2}|=0.17(3)$ for the prolate and the oblate bands, respectively, have been extracted. The results also shed new light on the mixing between different shapes.
