Abstrakt: Lifetimes of states in the magnetic band in 193Pb have been measured with the recoil-distance Doppler-shift (RDDS) method. This band is built on the Iπ = 29/2− isomer (Eex = 2584 keV, T1/2 = 9.4 ns). High-spin states in 193Pb were populated in the 170Er (28Si, 5n) reaction at 149 MeV. The nuclear γ-decay was detected with the GASP spectrometer in combination with the Kln plunger device. These results provide for the first time a complete set of experimental observables for such an excitation in atomic nuclei.
