Abstract.

Exited states in 134Pr were populated in the fusion-evaporation reaction 119Sn( 19F, 4n) 134Pr. Recoil distance Doppler-shift and Doppler-shift attenuation measurements using the Euroball spectrometer, in conjunction with the inner BGO ball and the Cologne plunger were performed at beam energies of 87MeV and 83MeV, respectively. The measured B(E2) values within the two chiral candidates bands are not identical while the corresponding B(M1) values have a similar behaviour within the experimental uncertainties.
