Magnetic moments of low-lying levels in Br-81 have been measured using
Coulomb excitation of Br-81 beams and the technique of transient magn
etic fields with Gd as ferromagnet. In addition, lifetimes have been r
edetermined for several states employing the Doppler-shift attenuation
method and mixing ratios of gamma-transitions were deduced from angul
ar correlations. The data are discussed in the framework of the partic
le-vibrator and the particle-rotor coupling models.
