Recoil-distance measurement of lifetimes of rotational states in /sup 1/64Dy

; ; ; ; ;
Lifetimes of the 4/sup +/ to 12/sup +/ levels in the ground state rotational band of /sup 1/64Dy have been measured by means of the Doppler-shift recoil-distance technique. Our best values for the mean lives of the 4/sup +/--12/sup +/ states are 286 +- 15, 39.0 +- 1.9, 10.4 +- 0.7, 3.7 +- 0.8, and 1.6 +- 0.8 ps, respectively. The corresponding B (E2) values exhibit a spin dependence consistent with rigid-rotor predictions. Within the respective experimental uncertainties, previous results obtained by multiple Coulomb excitation and Doppler-broadened line shape methods are in agreement with the present recoil-distance values.
