Abstract
The recoil-distance Doppler-shift and Doppler-shift attenuation techniques were employed to determine for the first time lifetimes of high-spin states in Cd-104 in the time range 0.3 ps less than or equal to tau less than or equal to1.2 ns. The nuclei were populated using the compound nucleus reacti on Ni-58(Cr-50, 4p) and the gamma radiation from their decay was detected w ith the GASP spectrometer. A total of 34 reduced transition probabilities a nd limits for 18 further transitions were extracted providing a rich basis for a comparison with theoretical calculations. In addition, the lifetime d ata contained new information urging for a revision of the published level scheme of Cd-104. In particular, a magnetic dipole band recently establishe d and interpreted as magnetic rotation is shown to he not existing. The new experimental results in Cd-104 are discussed in the frame of the interacti ng boson plus broken pair model.
