The transition strengths for the low--lying levels of {sup 122,124}Ba have been determined analysing the Recoil Distance Doppler Shift data by the Differential Decay Curve Method. The trend of normalised B(E2) reveals a drop in correspondence of the 8{sub 1}{sup +} state. This feature is also present in {sup 122}Ba: entering the backbending region the interplay between collective and quasiparticle degrees of freedom have to be carefully taken into account.
