Lifetimes of low-lying states in $^{102,104}Cd$ were determined by using the recoil distance Doppler shift technique with a plunger device and a Ge array consisting of five HP Ge detectors and one Euroball cluster detector. The experiments were carried out at the Cologne FN Tandem accelerator using the $^{92,94}Mo(^{12}C,2n)^{102,104}Cd$ reactions. The Differential decay Curve Method in coincidence mode was employed to derive the lifetime of the first excited $2^+$ state in both nuclei and the first excited $4^+$ state in $^{104}Cd$. The corresponding E2 transition probabilities agree well with large scale shell-model calculations. Work supported by DFG grant 391/3-2.
