Lifetimes of states in the vi(13/2)(-1) circle times pi (i(13/2)h(9/2))(11-) magnetic band in Pb-193 have been measured with the recoil-distance Doppler-shift (RDDS) method. This band is built on the I-pi = 29/2(-) isomer (E,, = 2584 keV, T-1/2 = 9.4 ns). High-spin states in Pb-193 were populated in the Er-170 (Si-28, 5n) reaction at 149 MeV. The nuclear gamma-decay was detected with the GASP spectrometer in combination with the Koln plunger device. These results provide for the first time a complete set of experimental observables for such an excitation in atomic,nuclei.
