Lifetimes in ${}^{114}\mathrm{Te}$ were determined using the recoil distance Doppler-shift technique with a plunger device coupled to five HP Ge detectors enhanced by one Euroball cluster detector. The experiment was carried out at the Cologne FN Tandem facility using the ${}^{93}\mathrm{Nb}$(${}^{24}\mathrm{Mg},p2n$) reaction at 90 MeV. The differential decay curve method in coincidence mode was employed to derive lifetimes for seven excited states, whereas the lifetime of an isomeric state was obtained in singles mode. The resulting $E2$ transition probabilities are shown to be very anomalous in comparison with the vibrational energy spacings of the ground-state band.
