Popis: | Exited states in $^{134}$Pr were populated in the fusion-evaporation reaction $^{119}Sn(^{19}F,4n)^{134}$Pr. Recoil distance Doppler-shift and Doppler-shift attenuation measurements using the Euroball spectrometer, in conjunction with the inner Bismuth Germanate ball and the Cologne plunger, were performed at beam energies of 87 MeV and 83 MeV, respectively. 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 |
