# Lifetime Measurements in $^{134}$Pr and Chirality in Nuclei

Abstract : Lifetimes of exited states in $^{134}$Pr were measured be means of the recoil distance Doppler-shift and Doppler-shift attenuation techniques. The experiments were performed at IReS, Strasbourg using the EUROBALL IV spectrometer, in conjunction with the inner BGO ball and the Cologne coincidence plunger apparatus. Exited states in $^{134}$Pr were populated in the fusion-evaporation reaction $^{119}Sn(^{19}F, 4n)^{134}$Pr. Reduced transition probabilities in $^{134}$Pr are compared to the predictions of the two quasiparticle+triaxial rotor and interacting boson fermion-fermion models. The experimental results do not support the presence of static chirality in $^{134}$Pr underlying the importance of shape fluctuations. Only within a dynamical context the presence of intrinsic chirality in $^{134}$Pr can be supported.
