Lifetimes of excited states in 148Gd were measured using the recoil distance method with a plunger device coupled to the EUROBALL Ge detector array. The differential decay curve method in coincidence mode allowed the unambiguous determination of lifetimes of more than 20 excited states. The obtained transition strengths are in good agreement with the shell model calculations. The effect of the Z=64 subshell closure on the $B(E2:2^+ \rightarrow 0^+)$ reduced strengths above the N=82 magic number is discussed.
