Abstract
The Doppler-shift attenuation method was used to measure lifetimes of yrast states in $^{166}\mathrm{Yb}$. Values of $\ensuremath{\tau}$ range from 0.16(2) ps at ${24}^{+}$. to 0.05(1) ps at ${34}^{+}$. The $B(E2)$ values decrease from 240 to 120 single-particle units in this spin range, indicating a loss of collectivity which likely reflects a change of the nucleus towards triaxial shape. The side-feeding times are consistent with rotational cascades having moments of inertia 25% larger than the yrast sequence or $B(E2)$ values around 60 single-particle units.
