The recoil-distance Doppler-shift and Doppler-shift attenuation techniques were employed to determine for the first time lifetimes of high-spin states in 104Cd in the time range 0.3 ps≤τ≤1.2 ns. The nuclei were populated using the compound nucleus reaction 58Ni(50Cr, 4p) and the γ radiation from their decay was detected with the GASP spectrometer. A total of 34 reduced transition probabilities and limits for 18 further transitions were extracted providing a rich basis for a comparison with theoretical calculations. In addition, the lifetime data contained new information urging for a revision of the published level scheme of 104Cd. In particular, a magnetic dipole band recently established and interpreted as magnetic rotation is shown to be not existing. The new experimental results in 104Cd are discussed in the frame of the interacting boson plus broken pair model.
